Installation

• Download Arnold for 3ds Max from your Autodesk Account. See Download Arnold for more information about downloading MAXtoA from your Autodesk Account.
• Follow these installation instructions.

Bug Fixes

• MAXTOA-1960 - By default, MAXtoA does not show Arnold RenderView on render nodes (for example, Backburner clients). If you do want to see the Arnold RenderView, you can now use the environment variable MAXTOA_USE_ARV_IN_BACKBURNER, with the options 0 = Off, 1 = display if enabled in the scene, and 2 = always show it for all scenes.
• ARNOLD-16840 - Fixed custom AOV settings resetting when in interactive mode.
• ARNOLD-17049 - Fixed bloom rotation in aperture mode for angles below -180°
• ARNOLD-17058 - [GPU] Fixed incorrect per-depth ray counts reported in stats.
• ARNOLD-17076 - Fixed random missing lights when using light_group and shadow_group on ginstance.
• ARNOLD-17088 - Fixed random crash when using curves and points nodes with min_pixel_width.
• ARNOLD-17140 - Faster procedural node destruction when most of its nodes are modified. Fixes very slow instancer destruction.
• ARNOLD-17149 - [GPU] Fixed small per-instance GPU memory leak.
• ARNOLD-17151 - Fixed an incorrect "Rendering CPU utilization was only 0%" message being reported when utilization was greater than 0%.
• ARNOLD-17171 - Fixed AiTextureTxFileNeedsUpdate returning false when colorconvert arguments contain empty spaces.
• usd#2467 - Hidden primitives do not show up when turned visible
