I went through Christopher Orth's tutorial series and he has us use GameObject: Destroy Self to clean up objects. I'm doing that with a cube which has a size of 38, 115, 1 and a texture mapped just to the front of a small pot. It is at z translation 9, in front of a "screen" object on which I've mapped a background image. For some reason, when the object is destroyed, it leaves behind a grey graphics "hole" in front of the background, in the shape of the object.
Has anyone else seen this, and how do I fix it please? Thanks!
EDIT: Also note, this shows up in the build as well.
