Hello, I downloaded the Pixar kitchen scene from Pixar and opened the rug asset as a USD file. It's about 26k polygons ( unsubdivided mesh ) and only 352kb in size. Converting the rug to a Scenekit or OBJ file increases the file size to 3.7MB! About 10x larger ! How did Pixar manage to optimize/ export a 26k polygon model with a size of 352kb? Is this only possible using their Presto proprietary software ? Is there special settings we need to used to export models created in Maya or 3ds Max with the same file size optimization? The Rug model is 3.7mb when exported as a USD file from 3ds Max.
