Title: Does the color value affect the diffuse if there is a map assigned to it?
Post by: actrask on 2019-06-12, 16:31:26

I've found that having a color value lower than 1.0 in the reflection slot affects the output of the reflection regardless if there is a map in there or not. Is the same true for the diffuse channel?

Diffuse color does not affect the texture used in diffuse slot.
Diffuse level does affect the texture.
If you are using some diffuse color (e.g. red) and a texture, and you scroll down to the list of textures in the material editor ("Maps" rollout) and you lower the "Amount" for diffuse, this will blend between the diffuse texture and the diffuse color. So if you change it from 100 to 50, this will show 50% of your texture and 50% of red-ness. This is the default behavior in 3ds Max (AFAIK).

Do the reflection inputs react the same way? What is the relationship between the reflection level and reflection color?

Multiplication.

(Reflection Colour swatch | Reflection Colour map) * Reflection Level = final reflection output.

Great info all around, and great tip about blending the color into the map via the % values at the bottom. I would always setup mix nodes to do that, thanks!
