Arnold Alembic Geometry shader assignment

[pedro_benjamimBY6S3]

Hello,

We're trying Arnold after many years in Vray and RS. Since we use 3dsmax as our scene assembly software, we bring a lot of alembics from Houdini and C4D. We're used to VrayProxy that works for both renderers, and in Arnold we have the Alembic Geometry. However i'm having an hard time figuring out how to assign multiple shaders to the same abc file?

Tried using the "User Data RGB" with "mtlID" but nothing is working.

Tried Multisub from Vray but maps aren't being read (only colors)

Tried OSL Material ID » OSL 1 of N » works in VrayProxy rendered in Arnold but motionBlur is messed up.

Tried same OSL workflow in Arnold Alembic Geometry and the IDs are gone (but motionBlur is correct)

What i'm looking for is a way to assign multiple maps to different face ID / material ID in the same alembic file.

Using native alembic from max is out of the question.

Any help?

Thanks,

Operators can be used to override shaders inside a procedural.

You can also export to .ass from Houdini/C4D and import as a procedural in 3ds Max.

You can also export shaders as .ass and import them into Arnold for 3ds Max (MAXtoA).
