Working on the solution for How to use transmissive voxels with color gradients? to be transmissive instead of reflective, I have a problem that I do not understand (Blender 2.79):
The gradient that is meant to be linear does not blend in a linear way in my eyes. Instead the gradient seems biased to wards black or darker colors. Even when I try to apply gamma correction, the gradient does not improve.
As I'm a beginner with blender, it's possible that I mad some mistake due to misunderstanding, so please tell me what I did wrong, and preferably how to fix it.
And here is how my attempts look:
Remark: The first image on the second row does not match the view angle of the cube in the first row, but the second one does. Finally, this is my node setup (hoping that's enough for the expert to understand):
The result I'd like to see should be as smooth as this if possible:
Unfortunately the emissive version does not have smooth gradients:
