Hi,
I need some help. I have my game renderer and it works ok, but at some point of time I add another Object3D (it is added to world from the beginning but is invisible, so I change only its visibility) and when it appear, for a moment my game slow down, fps too. This action occurs only when I first time do this manipulation. When I repeat it again everything looks ok. My Object3D is't complex.
I don't know what is going on. Do you have any solutions for this problem?
