Hey guys,
my problem is really annoying!
It's driving me crazy.
So, here my problem, I created my models in Hexagon and export them into "3ds" file format, following I import this model in Ultimate Unwrap 3D Pro and gave that model a UV texture.
Finally I export the model with Ultimate Unwrap 3D Pro into the "x" file format and try the model in fps creator.
Thats the result:
The models are not effected to the light sources.

This model is full textured and without shaders.
You can try this out, download of that model below.

I hope, someone can help me.
Greetings
