Hey folks.

When I perform a USD export of a character from CC4 and then open it up elsewhere in another DCC the materials do not link up despite that they are exported. I'm a Houdini user. When auditing the sublayers and scene data it is shown that the prims are authored so that materials are unbound as shown in the screenshot. This is an error or oversite at the time of export from CC4 I believe. I noticed the same thing happens for iClone 8 when testing. I validated this as true in multiple DCCs when importing USD characters from Reallusion apps.

There is no option during your export process for the user to explicitly ask for material binding. This means the user then has to manually do this in their DCC which is incredibly tedious. I would like to know if you have a workaround that I'm not aware of to resolve this on export and if not can you please update CC4 and iClone 8 with some urgency to address this as this is a major time sink in a production sitution.

Thank you for your time and insight!

Regards,

Tobias

p.s.

I'm aware that your export works in Omniverse but I'm certain some other step is occuring under the hood in that exchange. A stand alone USD file should be universally usable in DCCs that support it, not just Omniverse. Thank you again for taking a look at this!
