Workflow for converting geometry in SOPs/OBJs into USD? Jan. 27, 2020, 10:16 a.m.

Creating multiple separate USD files from a single SOP node source using groups is not likely to be something we support. I'm not sure this is even possible given the way that SOP data is imported to LOPs (using the USD file format plugin). I'm sure it would be possible to create an HDA that does something like this (using the SOP Import's “Import Group” parameter and a For Each loop). But we currently have no plans to create such an asset.

On the other hand the Scene Import approach should work much better than it does, and that is a node that will definitely be receiving some attention in the coming months. Being able to control the save paths for each object is definitely one thing we'll need to add. I suppose we could add the ability to split a single SOP into multiple USD references in this node, but it isn't currently in the plan. I see a lot of complications with such an approach and the authoring of transforms on each group…

For now, I think what you've done referencing in each SOP separately is the best approach. You might improve it by using a For Each loop, and maybe using the Import Group parameter on the SOP Import. But again, the transforms would be a problem…

Render lops through pdg? Jan. 20, 2020, 11:11 a.m.

There are USD Render and ROP USD Output TOPs. Pointing a ROP Fetch at a Karma LOP probably doesn't work because the Karma LOP is a LOP HDA with a ROP inside, not a ROP itself. I expect you could point a ROP Fetch at the USD Render node inside the Karma LOP?

Transforms and LOPs Jan. 13, 2020, 2:13 p.m.

I'm still not seeing this. Could you please submit a bug report? Then our support staff and other developers here can try to reproduce it… Thanks!
