Unity normal map problem.

S@murai

Hello!

I have a problem with normal maps in Unity. When I apply one on a mesh seams are still sharp edges and seams are still visible which is not a case in Unreal.
I've already tried flipping green and red channels of normal map but without success.
Hope You can help me.

Try this...
In the Inspector for the FBX file…
Set Normals to Calculate.
Set Smoothing Angle to 180.
Set Normals to Import.
Set Tangents to Calculate.

Or you can stick this file in an Editor folder in your Assets directory and it'll do it automatically on import (you'll have to reimport any existing meshes afterwards).

Also, how are you baking the normal maps?

If I do it correctly it don't work for me.
I bake in Xnormal with cage. Every angle > 60 degree is marked as sharp and have split in UV. Normals look good everywhere but in Unity. I tried Marmoset, Xnormal Viewer, Unreal4 and Unity5.

Try this, you're probably not baking synced normals...

Also, for those normal maps to look best you should be running unity in deferred rendering.

Thank you guys! I double checked my normal maps and meshes and it seams I was wrong and blind. There are visible errors because I missed sharping few edges.
I'm so sorry!

I pulled a few all-nighters recently and that has to be an side effect

I'm working on this board:
