Improved handling of complex, layered MaterialX shaders. SideFX Houdini 20.5.278

The Vellum solver receives a minor but impactful tweak in 20.5.278. The substep handling for "wet" cloth (simulating absorption and mass change) is now deterministic. Previously, the same seed value could yield slightly different results on different hardware threads. This build introduces a thread-local storage fix, ensuring simulation reproducibility across render farms.

The 20.5.278 build demonstrated improved render stability with fixes for crash scenarios in Karma, enhanced material workflow reliability, and better AOV (Arbitrary Output Variable) support for rendering pipelines. For artists transitioning from Mantra to Karma, the build provided more robust depth passes for fire and smoke simulations. Locate the specific build number from the dropdown
