problem in getting rid of texture seams

[yangtsur]

being stucking with this problem for a while now, tried many ways googled from net but non of them worked. I did it step by step but the result is still the same... feel very frustrated.
What I did to my uv map, I used mirror for all parts of the body except body and head. It shouldn't be a problem right? I seen many ppl do the same thing to save more uv space.

it looks like your normal map is flipped. got no idea what program you used to bake it and which program your rendering in?

[yangtsur]

yes half of the normal maps are flipped becasue i mirrored uv islands. I use mental ray to render the model, didn't configurate much tho.

i use maya mental ray to render, with defult config and draft quality for quick look only. And I made normal map from Zbrush.

just try to invert green or red channels until you dont have seams anymore :D

[yangtsur]

inverting green or red channel is not working at all. the problem remains.
