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.
Linux Desktop Managers: Mari is officially tested on GNOME. While it generally works well on other desktop managers like KDE, most of our bug fixes will target GNOME. However some desktop managers like XFCE are not compatible with Mari and will not be supported.
*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.

There are no New Features in this release.
TP 374961 - Mari now uses a more optimal technique for listening to changes in the project colorspace settings to improve project load times.
TP 374974 - Color swatches now cache their corresponding colorspace values to improve rendering performance.
TP 348174 - Support has been added for importing EXR images containing arbitrary channel data.
TP 368815 / 366514 - When applying an 8-bit projector the projected image would end up darker than expected.
TP 372410 - When using custom OCIO Config files painting and baking multiple times on the same position on the geometry, Mari would create artefacts around the edges of the paint.
TP 372539 - When using the OCIO environment variable, to set the OCIO config to use, any GPU accelerated colorspace transforms would fail to register.
TP 358954 - Any colors picked using the Eye Dropper tool would be incorrect when Color Management was disabled and the View Transform is enabled.
TP 371392 - Any colors picked using the Color Palette tool would be incorrect when Color Management was disabled and the View Transform is enabled.
TP 373129 - The Input Colorspace option, on the View Transform toolbar, was not being shown after creating a new project with Color Management disabled.
TP 373174 - When changing the Working colorspace, in the new project dialog, the Blending colorspace would change back to the first item in it's list.
TP 360196 - When applying a filter to selected images, the preview didn't match the final output.
TP 372648 - In the gradient tool, the picked start and end colors didn't match in the preview and when painted.
TP 363511 - Applying a filter to selected images produced artifacts if the image was being used in a tri-planar projection.
TP 359194 - Toggling scalar data on and off, whilst painting flow vectors with color management disabled, would have an affect on what was displayed in the canvas when it shouldn't.
TP 373964 - Projects using custom OCIO configs would get an invalid colorspace warning when an image was loaded into the paint through tool.
TP 371937 - When applying a filter to the Current Paint Target the final results wouldn't match what was displayed in the preview.
TP 224395 - Applying a filter to the Paint Buffer, using a mask image, would end up unpremultiplying the result incorrectly.
TP 375581 - Changing the Blending colorspace, whilst there was paint in the Paint Buffer, would result in a perceptual change in color.
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 - 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 - 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
