I am using a normal mapping shader on a character and it seems the binormal acts weird.
I tried the same model in Unity3d and the normal mapping worked perfectly so it is not an issue of the model.

Example:
Picture

Look at his nipples. One nipples lighting is horizontally inverted.

I talked to a lot of people and it seems that this is a common issue.

It would be great if this could be fixed in the next version as it really lowers the quality of the normal mapping and creates really unrealistic lighting on some models.
