• At least 4GB RAM
• Display with 1680 x 1050 pixel resolution
• An NVIDIA or AMD* graphics card with the latest drivers
• 1GB of graphics memory
• OpenGL 3.2* or higher
*Displacement preview is currently only available on the cards and drivers that support OpenGL 4.0 or newer.
Recommended System Requirements
• 2.5+Ghz Quad-core processor

• 16GB RAM with additional virtual memory*
• Display with 1920 x 1080 pixel resolution
• An NVIDIA or AMD* graphics card with the latest drivers

Tested Workstation Hardware
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.

New Features
Shader Compilation
• ID 246716 - Shaders now require fewer recompilations (the spinning wheel) when performing certain repeated tasks, reducing the waiting time between performing an action and viewing the final rendered shader. See GPU > General > Shader Compilation in the Mari Preferences Dialog section of the Mari Online Help.
Colorspace Export Optimization
• ID 251019 - Some colorspace transformations have been introduced to allow Mari to bake the paint to disk at a faster speed. See Data > Channels > Export Transform in the Mari Preferences Dialog section of the Mari Online Help.
Lift Option in the Marquee Select Tool
• ID 245977 - After performing a marquee selection, you can now lift the texture from the current paint target to the paint buffer for further manipulation. See Marquee Select Tool > Lift Marquee Selection in the Tool Properties Palette section of the Mari Online Help.
Optimized Texture Unit Usage
• ID 246731 - Mari now combines multiple textures into one optimized unit, so that you can work on projects with a higher level of complexity, without reaching graphics capacity limits.
Baking Bake Point Nodes in the Node Graph
• ID 246218 - You can now bake the Bake Point nodes that have never been baked before or are out-of-date, directly in the Node Graph by right-clicking and selecting Edit > Bake Points > Smart Bake And Update. You can also bake the selected Bake Point nodes using the same menu. See the Working with Nodes and Node Graph Functions sections of the Mari Online Help.
Feature Enhancements
• ID 231484 - The UV View has been updated to reflect selection changes in the Node Graph.
• ID 240086 - Nodes using the Locator list attribute were always bound to their selected locators.
Now the Locator list attribute has its own transformation controls in case of an empty or deleted locator.
• ID 240928 - The Channel and Layer palettes' icons have been improved.
• ID 249581 - The environment light cache has been updated to prefix the artist's environment, so as to ensure the correct environment light cache is generated and used on the artist's machine.
• ID 264159 - mGo now includes extra colorspace options for Maya.
• ID 267533 - Mari now includes new channel presets for multiple workflow and shader types. For more information, see the Shading Networks > Channels > Creating Multiple Channels from Presets section of the Mari Online Help.
