Hi all,

I have a strange problem : Nodes are moving (PAT->LOD->Node.ive) depending
on a PAT and all the PATs have the same group for parent.
Theses nodes (planes) have the ground under them but, sometimes the planes
are hidden under the ground.

It happens when the camera it on a top-position (not side or face ) of the
planes and it depend on the point looked by the camera. Just modifying
camera's orientation make then appear.
If the camera if near of the plane nothing happen.

I have checked Z position, but it do not changed anormaly. I only see a
culling problem to have this problem.

Do you have already encountered something similar ?
How to solve this problem ?


See attached files to understand better what it looks like.

thanks,

Regards

Vincent.
