NOTE: Mari increases its level of performance with newer, more advanced hardware configurations. However, Mari is tested and capable of operating on many older, prior-generation systems. For this reason we are listing below-minimum requirements, which are recommended, and on which tests have been performed. Your particular needs may vary from that of other users.
*Displacement preview is currently only available on the cards and drivers that support OpenGL 4.0 or newer.
*The use of virtual memory improves stability and helps prevent data loss on large projects.
'Recommended' does not guarantee that it meets your particular needs.
The configurations listed below are those that The Foundry have tested with Mari. Due to the constantly changing nature and wide variety of computer hardware available in the market, The Foundry is unable to officially certify hardware. The list below can be used as a recommendation and does not guarantee that it meets your particular needs.
Please download and install the latest graphics driver from the NVIDIA or AMD websites, and ensure that you are using 8.982.1 drivers or higher for AMD cards.

Mari now uses a single OCIO color-picking colorspace to define all saved colors and color-picking tool colorspaces. This achieves a 'what you see is what you get' workflow when managing your chosen colors.
The Colorspace toolbar has been refreshed and renamed to the View Transform toolbar. Labels have been replaced with tooltips, controls have been combined, and there is now a visual indicator of the data type being viewed. The Color Manager controls are now hidden when OCIO color management is enabled.
We have introduced a new scalar monitor colorspace to the View Transform, allowing artists to view scalar data perceptually linear. In a scalar channel a linear ramp will now appear in a similar fashion as other 8-bit based imaging applications, rather than displaying the raw data like Nuke does. The information as used by Mari is still in the expected data format, providing the best results with the most artist-friendly workflow.
Mari now contains visual indicators in the Channels palette, to define whether a channel contains color or scalar data and to display the channel's bit-depth. This lets you manage channel configurations at a glance.
Mari now contains the OCIO Colorspace filter. This allows you to convert paint target and buffer's colors to another colorspace within the currently loaded OCIO config, without affecting any channel settings.
Mari's colorspace processing has been optimized. This results in faster project load times.
The existing GPU accelerated color management system has been extended for paint data to work with procedurals as well.
We have introduced new OCIO role names that Mari will now recognize and use to configure the project's colorspace defaults. For full details of roles and targets, please refer to the Project Settings topic in the Mari reference guide and the Mari Specific OCIO roles in Color Management knowledge based article.
When a new object version is added, Mari now attempts to match selection group's membership across to the new version. This allows you to define selection groups once and have them applied across all subsequent object versions. See Adding and Removing Object Versions.
TP 349013 - Mari no longer collects Usage Statistics and the related opt in or out Send Statistics preference has been removed from the Mari Preferences dialog, Preferences > Misc .
TP 284705 - The Height As Normal adjustment now has a Bump Space option to select a coordinate space to compute normal maps in. The new World option generates a seamless normal map in the world space position.
TP 286713 - In the Mari Preferences > Color tab a new Detect Path Colorspace option has been added to disable or enable automatic detection of the colorspace of an image from its filename.
TP 316474 - The view transform is no longer switched off when viewing in the context of scalar data, meaning that the Gain and Gamma controls can now be used.
TP 337248 - Mari now follows the default behavior for premultiplication within EXR files. Color values have been updated to be unpremultiplied on import and premultiplied on export by their alpha.
TP 342360 - A Color/Scalar toggle has been added to procedural color inputs to allow you to set the context in which the color is being used.
TP 337028 - The Color Manager palette has been renamed to Color Manager (View Transform).
TP 272098 -
Changing blending mode on layers and the paint buffer no longer requires as many shader recompilations, allowing for a more uninterrupted painting experience.
TP 335897 - Baking a bake point node is no longer slower than baking its node graph to a paint node.
TP 337651 - Blend modes are now cached to reduce the number of shader recompilations in Dynamic mode. For full details of this update, please refer to the following knowledge based article describing Blend Mode caching in Mari 3.4v1 and 4.1v1.
TP 324469 - Black or green dots appeared all over the mesh on 387.## NVidia driver series or above.
TP 226414 - Upgrading projects from 2.x to 3.x would result in images used by procedural layers and nodes being duplicated in the incorrect colorspace.
TP 243213 - Creating new projects was failing with large objects.
TP 310270 - Mari's import speed for images is now equivalent to Mari 2.6v5.
TP 270481 - Adding a geometry version from an Alembic/FBX file, via the Python API, did not work.
TP 279134 - Baking a Bake Point node inside a group was causing an object to turn red.
TP 322242 - Changing colorspace in project settings after deleting a tab in the Image Manager was crashing Mari.
TP 286379 - The Pixel Analyzer was displaying colors incorrectly.
TP 309574 - The Slerp tool was crashing Mari when the Up key was held down.
TP 311287 - When baking paint the destination texture would become brighter.
TP 311560 - Loading a multi-node gizmo was crashing Mari.
TP 321095 - Copying, pasting and importing nodes that contained backdrops incorrectly set the selected states of the backdrop nodes and resulted in unexpected behaviour in the Node Graph.
TP 166585 / BZ 51890 - Patches > Mirror and Transform operations did not work on paint nodes.
TP 175933 - The advanced blend mode curves would not work on a merge node unless they were enabled in the Layers palette.
TP 332307 - OS X only: Resizing a palette could overshoot the height limit when docked.
TP 312932 - The tooltip for File > Project Settings > Monitor has been updated to reference the View Transform colorspace rather than the Canvas colorspace.
TP 337502 - When importing Channels from a Session Script, the import would fail due to an AttributeError.
TP 234930 - When a 'Height as Normal' adjustment layer was added to a procedural cloud layer, a white or black halo would appear around the edge of the model in the viewport.
TP 246220 - Mari would freeze when the Tab menu for node or layer creation was triggered during a baking operation.
TP 336912 - When exporting a Session Script, remapping patches using GeoEntity.copyChannels() did not copy textures in the correct colorspace.
TP 268536 - OSX only: Turntables would render blank when the Unprojection > Shader Used, set in the Projectors Palette was assigned to a shader added in Mari 3.0. These included the AiStandard, RedshiftArchitectural and VRaymtl Shaders.
TP 268837 - Images with uppercase file extensions could only be imported through the Image Manager.
TP 274327 - Filling faces was not causing connected bake point nodes to become out of date.
TP 274340 - Deleting a node in the Node Graph could sometimes caused unselected Backdrop nodes to be deleted if they had been created using copy and paste or imported from a gizmo.
TP 275562 - The Brush Editor sometimes caused a crash during projection.
TP 279087 - Channels' lock and unlock icons were not updated when toggling between lock and unlock operations.
TP 280022 - Some layers, including graph layers, incorrectly displayed a procedural icon.
TP 284323 - Flattening a mask stack containing an empty paintable layer caused Mari to crash.
TP 312847 - After disabling the compute shaders preference some textures in the canvas would disappear and not render.
TP 313810 - Dragging a color swatch would display incorrectly.
TP 313854 - Toggling the scalar option of the current channel wasn't updating the view transform.
TP 314015 - Switching between two channels with differing colorspaces was causing issues with scalar data.
TP 316412 - Opening the Session Scripts export window when a layer stack in the current project contained a layer without any inputs would cause a python error.
TP 317867 - Texture transfer was blocked by dialogs that appeared due to Image Sets with missing UDIMs.
TP 328708 - The default colorspace, when importing into a channel or layer, wasn't being correctly set to Automatic, but rather to whatever the Channel's colorspace was set to.
TP 331333 - When un-projecting a projector, or rendering a turntable, with full lighting enabled, the image would export incorrectly.
TP 337377 - The export colorspace was only applied to the first layer in a channel on export.
TP 337468 - Importing Channels from a Session Script of an older version of Mari caused importing to error.
TP 341769 - Importing Channels with custom blend modes from Session Scripts failed. Importing Channels where one was referenced by the other from Session Scripts made in Mari 3.1 resulted in duplicate Channels being created.
TP 342290 - Selecting a UDIM through the patch selection tool was slower than selecting it through the Patches palette.
TP 216593 - The mask input on the sphere and cube map projector nodes have been removed as they had no function.
TP 207913 - Mari may crash, or operate with lower than expected performance, when using recent graphics drivers with some AMD cards.
There have been reports that Plays.tv and Raptr, which come bundled with the AMD FirePro drivers, can cause instability in Mari. If you are experiencing instability, please try uninstalling these applications.
TP 123514 / BZ 50886 - Session Scripts: Imported shaders don't have channels assigned.
TP 113036 / BZ 49131 - High polygon .obj files, exported using the OBJ Exporter plug-in, cannot be read back in to Mari.
TP 10157 / BZ 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.
TP 9854 / BZ 14985 - There may be a slight pause after importing textures when creating new projects, while Mari saves the project.
TP 64924 / BZ 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.
TP 10046 / BZ 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.
TP 9567 / BZ 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.
TP 126816 / BZ 51452 - When importing a gizmo, the nodes in the gizmo did not retain their organization if they were created using the item name in the menu.
TP 125961 / BZ 51263 - It is not currently possible to attach the Viewer node to standard Mari shaders, because they are hidden. As a workaround, you can click the View the current channel button above the Node Graph.
TP 125813 / BZ 51247 - Channel transfer doesn't transfer Graph Layers as expected.
TP 124611 / BZ 51082 - The Ambient Occlusion node's properties don't include a generate AO option.
TP 48970 / BZ 23010 - 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.
TP 17678 / BZ 19780 - A projector created in Ortho view in Mari does not re-project correctly in Nuke.
TP 13600 / BZ 17626 - It can take a long time to import very large or very high polygon count ptex models. The work-around is to assign a small uniform face size (1x1 or 2x2) on import, and then upres the relevant bits of the model as necessary after loading.
TP 13531 / BZ 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.
TP 64961 / BZ 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
TP 200836 - Scrolling in the Brush Editor or Tool Properties palette makes the scratch pad go blank.
TP 129292 / BZ 51771 - Removing, changing, or hiding subdivided objects takes a long time.
TP 126164 / BZ 51322 - Modo Render: The preview occasionally fails to update fully.
TP 125997 / BZ 51273 - Mac OS X 10.10 and above: Rendering is occasionally incorrect when using multiple lights.
TP 124233 / BZ 51049 - Texture transfer does not take object transformation into account
TP 123532 / BZ 50898 - Existing subdivision calculations are lost when recalculating, even if recalculation fails.
TP 100303 / BZ 46600 - Miscellaneous - Ambient Occlusion must be updated after any OpenSubdiv calculation.
TP 62668 / BZ 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. To work around this, set the locale (language) to English.
TP 60643 / BZ 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.
TP 37066 / BZ 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 workarounds 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.
TP 9758 / BZ 14201 - Linux only: Mari becomes unresponsive after the system is woken from sleep.
TP 9631 / BZ 13700 - Adjusting the Camera > Perspective settings for a Projector is not reflected on the canvas until the Projector is made Current.
TP 9363 / BZ 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.
TP 9342 / BZ 11874 - Mari doesn’t recognize 3-digit padded .obj sequences as animation
TP 8030 / BZ 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//.mari/TheFoundry/Mari.ini
These are the changes relevant to developers.
TP 286539 - A new argument for specifying colorspace settings has been added to the following Python methods:
TP 266897 - PySide2.QtHelp module can now be imported and used in Mari Python scripts.
TP 343565 - The Python MenuManager API has been extended to allow access to nested submenus.
TP 328026 - The new createChannel method is added to the Python NodeGraph class.
TP 285076 - Mari can now pythonically remap existing patches to new patches that were not used in a previous session.
TP 307980 - The Paint node and BakePoint node now contain API methods to access and set their file-space, bleed property, size, depth and how they are managed. They also now emit signals when those properties are changed.
TP 337267 - Mari now declares cubemapToken as the unified samplerCube type for use of custom GLSL function that takes in samplerCube argument for texture look up. Also mriTexture() and mriTextureLod() calls can be used to look up the texture using cubemapToken. For full details of this update, please refer to the knowledge based article describing How to create a RAW texture lookup call in custom GLSL by passing in a texture.
TP 344073 - Specific custom GLSL shaders were failing, due to the texture token type change from uvec2 to uvec4. A new MARI_VERSION shader define has been added to allow sharing custom shader code between Mari 3.4 and 4.1 and older versions. For full details of the new define method, please refer to the following knowledge based article which describes the MARI_VERSION updates for shader writers and development.
TP 351176 - Mari now properly disconnects a node via Python API Node.setInputNode() function.
TP 341978 - When creating a project using the Python API the initial layer generated did not contain an alpha channel.
TP 346314 - Pythonically querying the colorspace config got progressively slower each time the command was triggered.
TP 96008 / BZ 44770 - The Python API function mari.app.isProcessing caused Mari to hang if called in a callback of function mari.app.endingProcessing.
TP 101460 / BZ 46910 - Python channelAdded signal was emitted before a channel had colorspace settings properly initialized.
TP 313083 - The Python API was emitting too many deprecated warnings and it was difficult to evaluate the source of the warnings.
TP 279776 - Removing shortcuts, via the Python API, had no effect.
TP 268297 - A convert dialog was appearing asking for confirmation to upgrade, when loading a project from the Python console.
TP 306236 - A layer created using the Python API displayed a difference in colorspace settings, depending on whether or not it was created within a layer group.
