Solid Angle Maya to Arnold 5.2.1

The software developer Solid Angle is pleased to announce the availability of Arnold (or MtoA) 5.2.1 for Autodesk Maya. This update introduces Arnold 7.1.3.1 and is a minor feature release including several improvements in viewport rendering, OSL shaders, as well as several bug fixes.

5.2.1 - Date: 31.08.2022

Enhancements

Viewport Render improvements. Several improvements were done on the Arnold Render in viewport, including :
- Viewport Render Region now reverts to full frame when disabled (MTOA-1095)
- Progress bar no longer overlaps with status on low resolution screens (MTOA-1138)
- Model bar icons weren't resizing in hiDPI monitors (MTOA-1139)
- Added ability to set custom HUD color (MTOA-1155)
- Arnold HUD no longer overlaps with Maya's heads-up display (MTOA-1141)
- Toolbar icons were greyed out after turning render region off, in viewport full frame mode (MTOA-1153)
"Coat affect" attributes in aiStandardSurface : The attributes coat_affect_color and coat_affect_roughness are now exposed in aiStandardSurface UI
Render callbacks in Arnold RenderView : The pre/post render callbacks are now invoked in Arnold renderview as they were in Maya Renderview. For single frame renders, the post-render callbacks are invoked immediately after the render finishes, but during IPR they are only invoked when the viewer is closed or IPR is disabled (MTOA-1137)
Render through USD Cameras : When a USD file is loaded with mayaUSD, it is now possible to render through cameras that are part of this usd file (MTOA-34)

Incompatible Changes

Pre / Post Render callbacks are now invoked in a different, more consistent way, than in previous versions. Pipelines relying on the previous behaviour might need to be updated.

Bug Fixes
- MTOA-1160 Export selection with motion blur returns invalid cameras data
- MTOA-1081 "Bake Selected Geometry" doesn't always include displacement

- MTOA-1142 getLatestVersion was using legacy URL
- MTOA-1154 Prevent MtoA loading error when stereoCameras aren't loaded in Maya
- ARNOLD-10677 - smart opaque did not work on ginstances when source mesh is hidden
- ARNOLD-12486 - Rocky 8 linux crash in kick on startup
- ARNOLD-12487 - Crash when application exits
- ARNOLD-12508 - Camera visible cylinder lights sometimes disappear when animate
- ARNOLD-12544 - "Free Render" not initializing geometries in non-default universes
- usd#1220 Fail to override output filename when AOVs are duplicated
- usd#1234 Fix udim with relative paths

- usd#1272 Avoid prefixing the primvars before getting their value for converting them to builtin parameter

Arnold is an advanced cross-platform rendering library, or API, used by a number of prominent organizations in film, television, and animation, including Sony Pictures Imageworks. It was developed as a photo-realistic, physically-based ray tracing alternative to traditional scanline based rendering software for CG animation.

Arnold uses cutting-edge algorithms that make the most effective use of your computer’s hardware resources: memory, disk space, multiple processor cores, and SIMD/SSE units.

The Arnold architecture was designed to easily adapt to existing pipelines. It is built on top of a pluggable node system; users can extend and customize the system by writing new shaders, cameras, filters, and output driver nodes, as well as procedural geometry, custom ray types and user-defined geometric data. The primary goal of the Arnold architecture is to provide a complete solution as a primary renderer for animation and visual effects.

Arnold for Maya is an advanced Monte Carlo ray tracing renderer built for the demands of feature-length animation and visual effects. It uses the Open Shading Language to define the materials and textures. Arnold for Maya (or MtoA) provides a bridge to the Arnold renderer from within Maya’s standard interface.
