NormalMap usage in Lighting.j3md

Hello. I have baked my normal from blender. I know that it is baked properly. I have a few questions.

First. Do we negate both the X and Y normal settings, or just the X.

And when applying my normal map to certain meshes they come out like this:

The simply smoothed version looks better than a high res normal map…

ALSO if I use the TangentBinormalGenerator I get these errors for many verts (no errors with MikktspaceTangentGenerator):

WARNING: Angle between tangents exceeds tolerance for vertex 135.

for TangentBinormalGenerator this is an old post, I think still valid

double check your mesh in blender, it looks like there is extra verts/faces around the armpit
