Title: AO reacting to bump normals
Post by: Eddoron on 2018-02-23, 12:02:08
As some C4D shaders do, it would be nice to have AO and maybe other shaders that don't support it yet/upcoming shaders like curvature to react to the bumps normals.

This is useful for fine details that could be hard to model or ruin the topology/UVs.

Here's something similar in Substance Painter:

edit: This reminded me of the AO artifacts (https://forum.corona-renderer.com/index.php?topic=19069.0) .
Correct me if I'm wrong: It seems that the AO shader only takes the geometry normals into account, not the shading normals.
If it took the bump normals, then could that also solve the AO artifact problem?
How does the AO in Corona work?
