I'm authoring USD assets from Maya Bifrost and rendering them in Solaris using Arnold and I want to start using Octane as well. For sometime now I thought the only way to enable SubD for Arnold and Octane was to set an override because the SubD in both of these apps are specific and doesn't follow the USD scheme of just setting a type.
I've reached out to the devs for Bifrost though asking about this and it turns out there is a specific attribute schema that I can inject in the time of defining the mesh prim which speaks directly to Arnold
uchar primvars:arnold:subdiv_iterations = 3
token primvars:arnold:subdiv_type = "catclark"
Does octane have a similar schema that it can read off of the USD file?
Cheers
