Welcome to our RealityKit + SwiftUI Course! In this course, you’ll learn how to build an AR furniture app for iPhone and iPad.
In this video, we’ll go over what to look for when purchasing 3D assets for use in RealityKit apps.

Also, in MacOS Big Sur, it appears USDZ can be viewed in the Preview app. Very handy.
Great tips and content Ryan. In some of the USDZ files that we have experimented with we sometimes get a preview error, which isn't very descriptive but just says "Preview | Universal Scene Description Package | Zero KB". This happens when trying to view the USDZ file in Safari on an iPhone. Any help/suggestions is appreciated. Thanks and keep the great tutorials coming.
Awesome production quality and content! Would love to hear your thoughts on:
1) Sculpting 3D models in VR ( e.g. in oculus medium) and essentially downscaling them for use in AR, do you think this has potential to replace tradition 3D production pipelines?
2) Is it worth learning traditional 3D modelling now as an AR developer, or would it soon be a redundant skill, with more tools popping up to streamline this process?
Looking forward to your future videos!
@@realityschool thanks Ryan, got you, yes that makes sense to outsource 3D, intriguing will have a look at vectary 🙂
Care, sketchfab usdz is autogenerated and i allready bought some models whit visual bugs. I fixed the most of them using blender, but be aware, sketchfab generally doesnt refund.
Hey Ryan,
are u going to use .reality files in this curse? Iam really struggeling whit Gestures on reality files and would be happy to see some solutions by you. :)
Is there a limit on the file size to be easily used in AR apps? Or specifications like the tessellation, etc.?
Great question! For most apps, it is very likely that assets will be downloaded from a remote server. Assuming people on average have a 10-20Mbps download speed, I would try to have the file as small as possible so the user doesn’t have to wait too much. I found that using textures of 1080p or 1440p is sufficient for most consumer apps with small objects. 4k or 8k textures look pretty but can drastically increase file size. In terms of polygon count, it varies per device but I would not load in a scene (of objects) with more than 100k polygons. For iPad Pro I was able to push closer to 200k but it will def impact performance and battery life.
So without knowing your specific use case, I would recommend doing things as small as possible without compromising the user’s experience.
