I found a problem that seems to be the result of the rendering improvements:
Clipping! For example, I have one object that has it’s center not in the camera frustrum, the entire object is no longer rendered. So, parts of the object that should still be visible are no longer. Normally an object should be rendered if one of its faces is in “sight”.
Is there a way to force objects to render even if they are behind the camera?
Edit: It only happens to objects that had their original space moved about(vertex displacement). So I guess, that the new geometry is not taken into account…
