Hi Antonin,
I am glad you had this sorted it out. You may try to replace shaders with
yours. Its possible to set only fragment shaders and use fixed pipeline for
vertices by setting MainVertexShader and ShadowVertexShader to NULL.

You can just call frame() in the while loop (if I'm right).

No.. When I searched the mail archive I found the previously linked message. It
stated:
It's a bad thing to add/remove items to the scene graph inside an update

It's bad if you add/remove objects in an upper part of you graph (like a

Not sure why you would need to place the vegetation _exactly_ on the ground

HI Chris,
I haven't reviewed the code yet, but it does sound like from your
