Thanks to all who helped me hit the ground running with an alembic workflow moving animation from Maya to XSI for rendering.
I have run into something puzzling tough - I have a textured and shaded model in XSI where each subpart is referenced in (the total filesize for the models is about 3GB). I then load the alembic animation file attaching it to my local model based on naming convention. This basically works fine, but in last nights render one object (out of 4700+ objects) rendered with a wrong shader on a few frames. It gets its shader from a group in its parent model, there is no duplicate geometry, it is a standard Arnold shader so no 3rd party stuff that might not be present on all render nodes and it is not present in another group where it could get a different material, so I am wondering if somewhere here with alembic experience has come across something similar? Thanks - Morten
