I am updating my game to A8 ... I use a large model as the space background. It is a sphere, with the surface normals facing inside.

For some reason, depending on the angle of the spaceship, the entire background will disappear. It reappears when I turn the camera back.

I am wondering if A8 has some feature that might cause this issue that did not happen in A7.

I have looked under "culling" and "occlusion" in the manual, but I'm wondering if there is a better term to search for this problem (feature?)
