Jira AC-67 Vray Material can now have either Legacy Normal, Corona normal, or Vray normal plugged in to bump slot and if non of those, we add an Arnold 2D bump node, so bump slot should be rubust now from Vray -> Arnold
Jira AC-68 We inject an OSL invert node in specular roughness if there is something connected to the slot to get better roughness translation since Vray is reversed logic.
Jira AC-56: Fixed the constant spawning bump node that would destroy normals, now checked against ArchModels random asset and it works better now.
Jira AC-62: Vray MtlWrapper to Arnold Passthrough
Jira AC-58: Flipped specular roughness input with an extra Invert Color OSL node on top of the shader, so specular roughness should now be usable to some extend and translate much closer, I tested on a random ArchModels asset and it looks fairly close.
Jira AC-59: Legacy Falloff to OSL Falloff, this is first step to port Legacy Falloff, right now it just opens up for Arnold GPU rendering.
It gives users a chance to update legacy shaders, materials and lights from V-ray & Corona and other legacy constructs found in a default max install and render with Arnold, without having to manually convert everything by hand.
The Arnold Converter also contains custom OSL shaders, build with the sole purpose of replicating feature sets in the legacy nodes.
Supported features you can convert:
Vray 2 sided material
Vray light material to Physical Material & Arnold Material
