In: Filters/Normal Map
Normal Combine combines the details of two Normalmaps in a mathematically correct way. It is similar to the well-known "Overlay" method from other 2D image editing software, but does work slightly different internally (three options).
This is the best and most correct way to add 2D-generated Normalmap details to a baked map.
If you want to blend two Normalmaps without combining their details (using a mask, for example), you should use Normal Blend.
- Normal 2: Color Input
- Normal 1: Color Input
- Technique: Whiteout (Low Quality), Channel Mixer (High Quality), Detail Oriented (High Quality)
Sets which internal blending technique to use, trading in speed for quality.
