Great thanks for the tip! I've converted my textures to 16bit and now it works just fine.

What if I want to deactivate the normal maps when the mesh is far away in distance? to gain frame rate that is.

Can I do that? and how? the fx is still in within the mdl file, it's not attached by any script to the mesh, but I guess I could use the "extern" checkbox for that.

Anyway little help here please
