Quote: "another question..
I noticed that he model is not aligned with the x axis of the editor but start from deep so I must raise it manualy and if I press the enter key to press it to terrain it go down underterrain ..I set offx = 0 into the fpe file but it's the same how I can solve that?"
When you select entity from panel and before place it, press "U", so you notice the selection becomes red color, so you can place and raise it without probs.
This beaviours usually comes when model is not 0,0,0 coordinates.

Do you resize any entity via widge?
Imagine you've a wall larger than you need, so you risize it via Gizmo in editor, for fit yours need. In previews versions when you do that, the wall preserve their collision range, that mean, if your wall before is 2 meter large and you resize it to 80cms, the wall still have 2 meter collision range, and you can not pass trought, ignore if this behaviour is present in GG too.
