I have found that I have to copy this node and use it as in the attached image to set my UV sets when I import a model from Maya into Houdini. Is there another way for me to set the UV set name? Is there even another node I can use?
I see this node in the V-Ray API. Is there any way I can generate this node from a Python script? And why isn’t it in the regular Houdini node menu?
I think I have found some of my answers here: Application SDK
However, it is still unclear to me why these nodes must be manually created each time I use a .vrscene file to move a model from Maya to Houdini, and why that isn’t documented anywhere. This seems like a bug.
Hey @colin_hannon ,
This is the internal V-Ray name for the UV Channel (Name) VOP under the V-Ray Tab menu - LINK to documentation. It will look for a vertex set on the geometry with the same name as the “UV Name” parameter.
Alternatively, there exists the UV Channel (Index) VOP - LINK. I would advice against using it as it relies on the export order of the vertex channels (attributes) - which is not guaranteed to be the same between renders, especially if you add/remove some attributes.
However, it is still unclear to me why these nodes must be manually created each time I use a .vrscene file to move a model from Maya to Houdini, and why that isn’t documented anywhere
Those are automatically created when you import a material using the VRScene SOP → Import tab. How are you importing the VRScenes?
Best regards!
Thank you for the helpful reply!
