Normal map issue
polycounter lvl 8
Hi, I imported mesh and normal map from quad spinner Gaea but my normal map looks weird in unity ( black artefacts is the issue ) I have uploaded the image both with a normal map and without normal map please help me.
WITHOUT NORMAL MAP

Has the normal map been normalized? I would suggest checking the Unity docs about this shader... Does it renormalize or not?
There is a bigger problem, shown in both screenshots. The mountain peaks should use hard edges, instead of none, and the normal map should be rebaked.
That would improve shading, improve compression size, and reduce compression artifacts.
You are seeing the results of "method A" as explained here:
