This isn’t from the book specifically, but considering it is going off of info from within the book, I figured it would be ok to post it.
I am creating my own scene using using one of Kenney’s awesome asset packs. I have the snapping down decently, but for the life of me I can’t figure out why the geometry is randomly clipping when I run on a device:
It seems that random faces appear/disappear depending on the angle of the camera, but changing the Z-clipping of the camera changes nothing. In the editor it appears fine.
