RELEASE NOTES FOR MARI 2.5V1
New Features
Please download and install the latest graphics driver for your card from the
NVIDIA or AMD websites.
NOTE: Ensure that you are using 8.982.8.1 (AMD Catalyst 12.10) drivers
or higher for AMD cards.
Due to the number of cards available in the market, we are unable to test
every card and, therefore, cannot officially qualify all of them individually.
However, if your machine/GPU specifications meet the requirements
mentioned, theoretically Mari should work fine for you. If you encounter any
issues, please contact support@thefoundry.co.uk.
New Features
Mac Support
• Mari now supports Mac OS X 10.8.4 Mountain Lion with NVIDIA graphics
cards. See Mac OS X Tested Graphics Cards for more information.
Graphics Cards
• The following NVIDIA cards have been added to the Windows and Linux
tested list:
• Quadro K2000
• Quadro K4000
• Quadro K5000
• Support for the NVIDIA Texture barrier extension
GL_NV_TEXTURE_BARRIER has been added. If this is present, it helps
reduce performance slowdown while painting.
Preferences
Windows and Linux: Support for VSync options have been added. A new
preference control can be found in the Mari Preferences dialog, under GPU
> General > VSync.
Set the dropdown preference to either
• On,
• Off, or
• System.
Setting the option to On forces the canvas to update at the screen refresh
rate. System lets the OS determine the behavior, which could be on or off.
Turning it Off allows the canvas to update at any time, but can result in

tearing if the canvas is running faster than the monitor’s refresh rate. This
setting is OS- and driver-dependent.
Shaders
• A Custom Shader API and accompanying API documentation have been
created. This allows you to create your own shaders to use alongside the
default shaders in Mari. The Custom Shader API documentation has been
added to the Help > SDK menu in Mari.
The Shader API now contains Perlin and Simplex noise functions.
• The shader code has been re-factored to improve usability and to adhere
to the coding standard. Aspects, such as the appearance and behavior of
the code, have been made more consistent by these improvements.
• The option to set whether or not to Perturb Normals has been added to
the Shaders palette in order to stop displacement changing the surface
normals, tangents, and bitangents.
Miscellaneous
• The Smart Selection tool now has a progress bar to indicate how long is
left until Mari completes the action. The action can also be canceled at
any time. On the Tools toolbar, with the Select tool active, the Smart
SelType and Smart SelAngle fields have been renamed to Smart Type and
Smart Angle.
• BUG ID 34544 - The shortcut to step backwards for animation has been
added to the Shortcut Manager again. The shortcut is Ctrl+left arrow.
• BUG ID 34666 - The blend modes Add Normal Maps and Mix Normal
Maps have been added to the list of Painting Mode blend modes. These
modes allow accurate modulation between two RGB-encoded normal map
layers.
• BUG ID 35315 - You can now press the Tab key in the Layers palette to
create a layer by typing in the name, as with Nuke’s Tab key node
creation.
• BUG ID 36906 - Two new adjustment layer types, Linear To Log and Log
To Linear, have been added to convert from a linear colorspace to a log
colorspace. The conversion is the same as that found in Nuke.
• BUG ID 37128 - A new set of Perlin and Simplex noise functions with 2D,
3D, and 4D inputs has been added.

RELEASE NOTES FOR MARI 2.5V1
Feature Enhancements
• You can now export Ptex quad faces suitable for bilinear interpolation.
• The Ptex triangle-to-quad warping conversion methods have been
improved. Tolerance checks also prevent NaNs from causing out-ofbounds accessing on image data.
Shaders
• The shader component name Specular IOR of the Cook Torrance shader
has been renamed to Specular IOR Weight.
• Custom patch sizes now use the global ShaderInputs default patch size
when no patch size is specified.
• Error handling during shader bakes has been improved.
• BUG ID 36932 - You can now manually enable or disable mip-map
generation and usage on images used in shader network nodes. The use
of mip-maps on spherical projector layers has been deprecated.
Layers
• BUG ID 34568 - Procedurals can now be baked and exported using the
Export for Maya script, under Python > Examples.
Please refer to 34568 in the Developer Notes for additional information
on this enhancement pertaining to developers.
• BUG ID 34818 - Share As Channel in the Layers menu and Layers palette
context menu has now been renamed Share Layers As Channels, and
allows you to share all selected layers into a new channel.
• BUG ID 34879 - Blending properties could not be changed on layers that
had been cached.
Blending properties are still disabled for layers cached using the Cache
Up To Here function.
• BUG ID 36636 - The controls used to adjust the X, Y, and Z Offset
values for the Sphere Map Projector and Cube Map Projector procedural
layers now include incrementers. This enables you to adjust the values
with either the keyboard or the mouse. You can also hold Ctrl/Cmd while
adjusting the values to adjust the incrementer range.
• BUG ID 36896 - New mask image sets and paintable layers added to
mask stacks now have their colorspace set to Scalar so that they are not
processed through the Color Manager.
• BUG ID 38080 - A new Components dropdown has been added to the
Constant procedural layer. Components allows you to choose whether
the Constant procedural applies to RGB or RGBA components.

Shorctus and Preferences
• The preference Max Batch Index Size in the GPU settings has been
removed.
• BUG ID 34810 - In the Manage Keyboard Shortcuts dialog, the search
function has been improved so that incomplete search parameters still
return results that contain part of the search string.
• BUG ID 36216 - The shortcut Alt+drag and drop for channels now
duplicates the dropped channel.
• BUG ID 37699 - Mac OS X only: Tools that used the Meta key have now
been switched to use Cmd+Shift instead. The Meta key (Ctrl) on the Mac
operating system is used to bring up the context menu.
Miscellaneous Improvements
• The canvas maximum frame rate has been improved by changing the
update mechanism.
• The memory usage in selection topology for the Smart Select tool has
been optimized.
• Image format extension checks are no longer case-sensitive for many
nodes in Mari.

Known Issues & Workarounds
Known Issues &
Workarounds
Mari Tools
• BUG ID 15810 - The black borders at the edge of the canvas in
Perspective view are selected, if an object overlaps the borders when a
selection is made using the Marquee Select tool, with the selection mode
set to Magic Wand.
• BUG ID 13640 - The Blur tool can be slow to use on the initial stroke.
Wait for Mari to process the blur before applying a second stroke.
• BUG ID 13481 - Making a selection using the Marquee Select Tool with
the selection mode set to Magic Wand sometimes ignores regions that
are completely surrounded by other selected regions, despite differences
in color.
• BUG ID 13394 - Using the Select Items tool with the Facing set to Front
to select and hide a portion of faces causes some of the faces within the
selection to remain visible when zoomed in.
To catch all selected faces, either:
• select Facing > Through instead of Front, or
• zoom in closer to the object.
Shaders
• BUG ID 34729 - Mari displays a rendering error on the canvas when it is
unable to create a shader. More information has been included to help
you determine the cause of the error. Some solutions might be to hide
groups and layers, or to cache parts of your layer stack until a shader
can be created.
• BUG ID 34679 - On extremely large projects, issues can arise with
shader limits and reaching the maximum allowed texture slots available.
To avoid reaching these shader limits on large projects, try the following
workarounds:
• hide groups and layers, or
• cache groups and layers.
Layers
• BUG ID 34690 - Flattening or caching layers or channels on complex
projects may cause Windows to reset the graphics driver due to the long
processing time. To work around this issue, you can try to flatten or
cache fewer layers at a time, or reduce the value of the Max Render Size
For Baking setting. This setting can be found under Preferences > GPU >
Baking and Projection.
Reducing this size breaks the flattening or caching operation up into
smaller pieces, which individually take less time to calculate, and thereby
avoids a Windows graphics driver reset.

RELEASE NOTES FOR MARI 2.5V1
Known Issues & Workarounds
• BUG ID 26460 - Painting a mask in a Mask Layer Group sometimes
results in unexpected paint results. To prevent this from happening,
either:
• Use a white “color” layer at the bottom of your mask stack. Any layer
used over this initial “color” layer should then be fine, or
• If you want to create a mask in a Mask Layer Group, simply add
another layer on your Mask Layer Group instead, and paint white into
it to create a mask.
Importing and Exporting
• BUG ID 29386 - When using the Export for Maya script, Maya’s viewport
may incorrectly show some patches as transparent. This can be resolved
by selecting High Quality Rendering or Viewport 2.0 from the Renderer
menu within Maya.
• BUG ID 16324 - Windows only: you cannot currently import an image
into a channel using a relative file path. To work around this, use an
absolute path when importing images.
• BUG ID 14985 - There may be a slight pause after importing textures
when creating new projects while Mari saves the project.
Nuke<>Mari Bridge
• BUG ID 23010 - Nuke<>Mari Bridge: If Mari crashes when receiving
incoming components from Nuke when the Virtual Texture Type is set to
Float, lower the Virtual Texture Size to a value below 8192x8192.
• BUG ID 19829 - Nuke<>Mari Bridge: Unprojecting a displaced piece of
geometry does not project correctly in Nuke.
• BUG ID 19780 - Nuke<>Mari Bridge: A projector created in Ortho view
in Mari does not re-project correctly in Nuke.
Python
• BUG ID 37601 - Python: The QFileSystemModel class PythonQt binding
is missing. The QDirModel class may be used in some cases as a
workaround.
• BUG ID 16616 - Python: PythonQt sometimes crashes when adding
temporary objects to layouts, or compound widgets such as
QTreeWidget. This is because of incorrect reference counting. To work
around the problem, always store a reference to every GUI item until you
are sure it is no longer needed.

RELEASE NOTES FOR MARI 2.5V1
Known Issues & Workarounds
Ptex
• BUG ID 17626 - It can take a long time to import very large or very high
polygon count Ptex models.
The workaround is to assign a small uniform face size (1x1 or 2x2) on
import, and then increase the resolution of the relevant bits of the model
as necessary after loading.
• BUG ID 17618 - Ptex does not bake properly if the resolution of the face
is too small.
The workaround is to increase the resolution of the selected faces you
are having problems with.
Graphics Cards
• BUG ID 37378 - Windows: With driver version 320.49 and before, we’ve
seen performance issues as well as timeout detection and recovery
issues with the NVIDIA GeForce GTX Titan graphics card.
The beta driver 326.80 appears to fix these problems. Please try to
update the graphics card driver version if you are experiencing these
issues.
• BUG ID 36260 - The AMD Catalyst 13.4 driver has been blacklisted due
to a known issue resulting in baking artifacts.
If you experience any problems of this nature, try rolling back to the
13.1 driver, as this should resolve the issue.
• BUG ID 18457 - Using NVIDIA graphics cards from the Fermi series with
drivers older than version 270 results in various rendering issues when
the Virtual Texture Type is set to Half or Float.
To resolve this, please download and install the latest graphics driver for
your card from the NVIDIA website.
• BUG ID 12567 - Enabling Sync to VBlank in NVIDIA settings can
drastically reduce Mari’s performance. If you experience very slow
interaction, even with low-polygon models, on one of the Windows and
Linux Tested Graphics Cards, navigate to:
• Linux: NVIDIA X Server Settings > X Screen 0 > OpenGL Settings and
turn off Sync to VBlank.
• Windows: NVIDIA Control Panel > 3D Settings > Manage 3DSettings >
Vertical Sync > Force off
Then, restart Mari.
Miscellaneous
• BUG ID 33293 - Linux: Launching Mari with the language set to one
without certain character symbols resulted in Mari failing with an error
that the specified transform could not be loaded.

RELEASE NOTES FOR MARI 2.5V1
Known Issues & Workarounds
To work around this, set the locale (language) to English.
• BUG ID 31946 - Sometimes paint is not baked because of memory
management issues on the graphics card. This can be due to issues such
as a high resolution paint buffer, a high bit-depth paint buffer, large
virtual texture size, or even a large scale value on the paint buffer
transform. These issues can usually be identified by glError: 0x505 out
of memory messages in the log.
Try reducing any or all of these values to prevent it happening. Graphics
drivers are continually improving, so it’s also worth checking whether
upgrading your drivers resolves the problem.
• BUG ID 20510 - If you find that the startup time for Mari is longer than
usual, please check that the LIC files in your RLM licensing data folder do
not refer to obsolete server ports. If they do, place them in another
directory and restart Mari.
• BUG ID 20021 - Textures in the canvas intermittently switch between
lower and higher resolutions.
This issue is more likely to occur if your virtual texture resolution is low,
and you're working on a complex model with displacement. Possible
work-arounds include increasing your virtual texture size, reducing the
number of channels Mari has to access at once (for example, by reducing
the number of channels required for the current shader), to reduce the
patch resolution of patches in the channels used in the shader, or to use
a smaller canvas window or monitor.
• BUG ID 14201 - Linux only: Mari becomes unresponsive after the system
is woken from sleep.
• BUG ID 13700 - Adjusting the Camera > Perspective settings for a
Projector is not reflected on the canvas until the Projector is made
Current.
• BUG ID 13571 - Launching a new version of Mari for the first time, when
a config file exists from a previous version, sometimes results in an
object not appearing in the Ortho view.
To solve this, close Mari, delete the following config file and relaunch
Mari:
• Linux: ~/.config/TheFoundry/Mari.conf
• Windows: C:/Users/<login>/.mari/TheFoundry/Mari.ini
• BUG ID 13294 - Windows: Mari sometimes crashes when trying to load
data on large projects due to the program exhausting all Window
manager objects.
To reconfigure the user object limit:
• Open regedit and navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\NT\CurrentVersion\Windows, and
• Edit USERProcessHandleQuota to a larger number.

RELEASE NOTES FOR MARI 2.5V1
Developer Notes
If this number gets too large, you may also have to modify GDIProcessHandleQuota.
• BUG ID 12102 - Current brush settings do not get saved as part of the
project. Instead, Mari reverts to the default settings when you close and
relaunch it.
• BUG ID 11874 - Mari doesn’t recognize 3-digit padded .obj sequences as
animation.
Developer Notes
These are the changes relevant to developers.
New Features
• The module mari.current has been added to the Python API.
• A new section for workflow information has been added to the Custom
Shader API documentation.
• Information exclusive to shaders has been added to global uniforms and
state members in the Custom Shader API documentation.
• Additional information on the Layer.hasMask() function has been added
to the Python API documentation.
• BUG ID 34568 - The function Layer.groupStack() has been added to the
Python API.
• BUG ID 36142 - The Layer.siblingSharedLayerList() function has been
added. This function returns the list of other layers that share resources
with this layer.
• BUG ID 36165 - The following functions have been added to the Python
API:
• AdjustmentLayer.primaryAdjustmentType()
• AdjustmentLayer.secondaryAdjustmentType()
• ProceduralLayer.proceduralType().
These provide a reliable way to retrieve the types of adjustment or procedural layers, and in a form that is more consistent with other functions. The existing similar functions, such as proceduralName(), have now
been deprecated.
• BUG ID 36251 - The GeoEntity.createStandaloneShader() and
GeoEntity.createDiffuseSpecularShader() functions have been added to
the Python API. The function GeoEntity.createShader() has been
deprecated.

mari.projects.archived have been added.
• BUG ID 34698 - The new function Layer.setName() has been added to
the Python API.
• BUG ID 34727 - The LayerStack.exportImages(),
LayerStack.exportImagesFlattened(), PaintableLayer.exportImages(), and
ProceduralLayer.exportImages() functions have been updated to accept
an optional list of UV indices to export.
• BUG ID 34805 - The new signals Layer.nameChanged,
Channel.nameChanged, and Shader.nameChanged have been added to the
Python API.
• BUG ID 35012 - The new functions mari.Channel.setName() and name()
have been added to the Python API.
• BUG ID 35031 - The new functions mari.Shader.setName() and name()
have been added to the Python API.
• BUG ID 35142 - The Indices page of the Python API documentation has
been reformatted to one page to make searching easier.
• BUG ID 35294 - Adjustment layer vector parameters, such as in the
Grade adjustment, were not properly processed through Python.
These can now be set from lists or mari.VectorN objects, and are
returned as lists.
• BUG ID 35941 - Python API: The Channel and LayerStack sub-classes of
metadata have been made so that metadata can be added to a channel.
• BUG ID 36169 - LayerStack.adjustmentLayerTypeList() and
LayerStack.proceduralLayerTypeList() are now static, so they can be
called through mari.LayerStack instead of requiring a LayerStack object.
• BUG ID 36213 - Layer.cacheLayer(), Layer.cacheUpToHere(), and their
uncache counterparts have been added.
• BUG ID 36250 - Metadata can now be added to shader classes in the
Python API.
• BUG ID 36252 - The GeoEntity.shaderStandaloneTypeList(),
GeoEntity.shaderDiffuseTypeList(), and
GeoEntity.shaderSpecularTypeList() functions have been made static.
This allows them to be called without a specific GeoEntity object.
• BUG ID 36481 - Python API export methods now have an option to
generate full patch bleed.
• BUG ID 37326 - Mari’s C++ API now supports using the Color class with
the Metadata class, allowing you to set and get metadata/user attributes
as colors.

Bug Fixes
The Foundry
• Context log tracking has been disabled.
• The Python API metadata flag METADATA_REMOVEABLE has been
deprecated due to a spelling error. The metadata flag
METADATA_REMOVABLE should be used in future.
• Mari occasionally crashed when fewer than four pairs of numbers were
given to MriGradient.
• Mari unnecessarily added Change Expression undo records, even with
non-undoable actions.
• BUG ID 15491 - Python API: PythonQt bindings were missing for some
enumerations and types.
• BUG ID 15922/36208 - The ImageSet.importImages() function did not
handle $CHANNEL and $LAYER token replacements properly in file names
during imports.
• BUG ID 23115 - The signals on mari.projects had inconsistent names.
Signals with new, consistent names have been added, and the old ones
have been deprecated. For example, mari.projects.projectOpened has
been superseded by mari.projects.opened.
The new signal mari.projects.opened has an optional extra parameter to
indicate whether the opened project has just been created.
• BUG ID 27592 - The default archive patch only applied to opening
archives and not to saving.
The way the path and file name parameters are combined in
mari.utils.getSaveFileName() has changed. Please see the Mari Python
API documentation for more information.
• BUG ID 34323 - Python API: The channel signals on GeoEntity were not
triggered correctly.
• BUG ID 35650 - The functions u_MriObjectCenter and u_MriObjectRadius
were not set to correct values for the evaluation stage.
• BUG ID 35940 - The Channel.flatten() function did not return the
resulting layer.
• BUG ID 36115 - The Application.startingProcessing() signal was emitted
for the nested start of certain sub-tasks, causing startingProcessing()
and endingProcessing() signals to be unmatched.
The startingProcessing() and endingProcessing() signals are now only
called for the outer-most start and end of the progress bar.
• BUG ID 36143 - The LayerStack.shareLayer() function did not create a
new shared layer at the top of the current layer stack when RefLayer was
None.
• BUG ID 36399 - A progress dialog appeared during Python export
function calls.
This is now suppressed to prevent it from appearing during the function.

MriImportTemplate metadata for a project was incorrectly added.
The ability to set the MriExportTemplate and MriImportTemplate metadata of an object has been added instead.
• BUG ID 37362 - Repeatedly clicking buttons in the shader console, such
as All and Reload Shader, caused Mari to crash.
• BUG ID 37509 - The LayerStack.groupLayers() layer_name argument was
not effective.
