System Information
windows 10, AMD HD 6970

Short description of error
buggy normal map baking.

Exact steps for others to reproduce the error
just bake normal map in cycles
then change render to internal
create new material, create new texture
in texture settings pick our noemal map
checkbox normal map in image sampling
influence:
off collor, on normal
go to material and set color intensity to 0
then if you look at the surface ull see this ugly bug that shows in unity for example.

This is caused of 8bit normal map.

bake and save your normal map with float buffer option checked to tiff 16bits

and about my screenshots, im not sure why there is banding in marmoset but in blender viewport there is no such glich. Ive baked this map one more time and in marmo i have it perfect now.
