normal map shading problem (max2011)

7oli

Hi guys!

I'm facing a problem with normal maps with my gun piece. This is a mirrored part and sharing one uv island. On the mirrored side a strange shading issue appears (i'm attached a screenshot). Checked the case of double vertices and found nothing. For the mirrored side i setting up different smoothing groups, and that not solving the problem. If anyone of you guys have an idea what is the problem, please let me know. Thanks. (sorry for my english) :shifty:

The problem appearing with max's default normal map shader, and with the xoliulshader too.

Quack!

Did you offset your overlapped UV islands before bake?

i'm baked only the half side, and after baking process i mirrored the other side. So there's no need to offset the other side when baking. After mirroring the two half piece is on the same uv place.

maybe you must rise a padding?

Go back and bake as one piece with offset UV's, see if the problem shows up again.

looks like that solved my problem. A small seam remained at the center but can't really visible, only if i zooming very close to it. thanks for the help.
