SItoA update 5.0.2.2 with CryptomatteAuthor: Rachid Hadj Abderrahmane
Rachid makes the latest Arnold Renderer version available to Softimage users via updates/patches of the latest (last?) SItoA release 4.1.0. That includes support for Cryptomatte and the new subsurface scattering method. Since his distribution package does not contain any binary files, the Arnold SDK has to be downloaded and the patches applied manually following the detailed instructions he gives in the si-community thread / his posted walkthough video.

Cryptomatte is becoming an industry standard for ID based object/hierarchy selection in compositing (Nuke/Fusion plugins provided).

Introduced in this si-community thread. Update posted here including a walkthough video: SItoA Update Core 5 0 2 2 & Cryptomatte

New plugins, tools etc.
