When camera is parented, everything disappears.

Ok,

small side project of mine - a plane game. The problem is, when I parent my camera to the plane, when I play, I can’t see the plane. Works fine if its not parented, but not if it is.

Ensure all parents have a scale of (1.0, 1.0, 1.0).
This is the most common problem.

Other possibilities:

  • one of the parents is not supported (e.g. a path) and does not exist in the BGE -> Children will not be added.
  • the camera is inside the model -> the faces are only visible to one side (in that case away from camera).

How do I check if the scale is (1.0)?
