I don't believe it is currently, but this might be a question for @Mike Farnsworth.

Just curious if anyone has been able to render interactive xgen caches in Katana? From what I gather so far from forums (Autodesk, Foundry, and this one) is that interactive xgen isn't treated the same way as the legacy xgen.

If I bring interactive xgen caches into katana via an Alembic_In node I get a scene graph location for the xgen of type "curves". This shows up in the viewer but does not seem to be getting rendered.

I don't see any warnings suggesting an issue with the inputs.

Anyone able to share in their success?

I don't believe so. KtoA's XGen support is based purely on the procedural plugin, which only runs once at the beginning of the render. Dynamic modification of the procedural contents would not be reflected inside of Katana. Interactive modification and look development of XGen assets should be performed in Maya, and then brought into Katana via KtoA for final scene assembly, lighting and rendering.

@Mike Farnsworth It is unclear to me whether an ArnoldXGen node will also work for inputting interactive xgen .abc cache files. At least, I have not had luck doing so. Can you please verify this?
