I try the demo version of gstudio A7 and, open the project sample about shader.
I replace the model with this (doom3 enemy model).
And...
this is the Results....

this picture without shaders



this is with shaders implemented



GREAAATTT.....

and look at the frame rates, still running FAST...

Note: this model is property of Id software (DOOM3), I use this for testing purpose only.

It is iteresting and it provides some 3d-lighting but it misses specularity. At least the metallic parts of this model should have some reflection of the light source.

Great model pack, even with normal maps included! However, they didn't include the specular channel...

If this model wasn't copyrighted, I'd make one myself. But it only seems like a waste of time...

I guess this is the NM shader from ShadersForGames, or whatever its called.
