Hi, I have trouble loading ply files generated by postshot. The (Vision Pro) app crashes without displaying an error.

The ply header is as follows:

ply

I'm unable to reproduce this with the tree.ply file you supplied; it loads fine for me. Is this with the sample app? What commit are you using? Can you give me more details that might help reproduce?

Huh, it's with the Apple Vision Pro app. Did it recently update? Let me try again (I was on vos2 beta, now that it's properly out it might have changed things)
