I have a collection file that looks like this, the rectangle’s normals are facing inwards, that selected object is the camera looking towards the other objects:
Try drawing the play area on its own render predicate material tag if you want the camera to be outside of it? I’m not sure of the exact problem if you can upload a simple sample that reproduces it would be helpful.
The model appears now, thanks! I draw models before everything else, but the camera won’t change from this position in my game, so I won’t run into any issues.
Unfortunately I have no idea what the dark patches are on iOS. It doesn’t happen locally on my Mac. The model is just a giant cube scaled on the Z axis and the front and back faces cut off.
The only things in my collection are the player sprite, enemy sprite, green box model, and the camera. It also only appears on my debug iOS app, I can’t reproduce it on a local engine.
That said, they render the model differently with the same render script. Could be something to do with that? Here are the two side by side, using the .zip I posted above:
