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.

Is it possible to setup a camera to use two-point perspective? I only found perspective and orthographic options in the Scenekit editor. Using two point perspective is a standard functionality that is available in every 3D software and is an Integral feature needed for correctly setting up camera views. Can't include links in here so please google ' 3ds max Camera Correction Modifier' and click on the first link. It explains how two point perspective works. If the current scenekit camera does not have this functionality, is Apple planning to add it and if so when would that happen? Thanks, Husam
