More control over Normal & AO map baking
« on: January 16, 2020, 05:39:01 PM »
It would be great to have more control over the Normal map baking process. The ability to tweak the dilatation width etc. As of right now they suffer from seam artifacts (the UV seams are clearly visible on the normal map under certain lighting angles). Also, can we choose the tangent space being used (Mikk/xNormal, Marmoset, Unity, UE4, Maya etc) ?

The ability to bake Bent Normal & Height map would also be great. But having more control of the Normal ( & AO) baking process would be nice.

Regards

Mak

All Normal maps baked in Metashape suffer from this:

Most importantly, being able to import custom vertex normals.

Integrating some sort of UV guiding would be great, such as Boundary First https://geometrycollective.github.io/boundary-first-flattening/

Alexey/Team,

Is normal map calculation done using Per-Vertex Binormal or Per-Pixel Binormal ?
