Inverted Normals on UV seams..

Defonten

Hi,

I'm stuck.. I painted a grayscale height map texture on a character (like muscles) and converted this grayscale texture to normals. The problem is when I do it by converting b/w texture to Normals with NDo I get terrible Seams on UV islands.. I marked the area on uv layout where those parts meet. Pls help. 

I tried inverting Green and Red channels of the problematic ares - didn't help.

A normal map made from 2d images will often have seams at uv edges. This is because the normal map does not have the gradients needed to twist the normals to work with the tangent basis: http://wiki.polycount.com/wiki/Normal_Map_Technical_Details#Tangent_Basis

Ok.. and what is the workaround for this??

Bake from a high poly model instead. Generating a normal map from a greyscale height map is mainly used for creating tiling textures on a completely flat plane or for adding additional details to a baked normal map, such as a fabric texture or rivet heads. It's not suitable for making large scale organic character details.

Agree. Thanks!
