I might check this out later. All I'll have to do is remove the line that transforms the normal tex to tangent space (as its already there )...

Looks interesting. Wait, I just remembered... I'm a horrible artist this is useless for me

yes, all normal maps may be suitable for 3dgs. it depends on the shader you're using.

it is [censored] awesome. At finally I found a normal map generator that I can use with 3dgs! I can see now all the bumbs and the details. Off course, it is not even close to Zb but, c'mon , it a wonderful starting.
