Necessary features for moss:
- Variated user defined color
- Softness in the displacement
- Specular change
- Uneven edges for patches
- Put in grout
- User can put where the moss will be with map or point color or use noise
Most of the above list has been accomplished, I'm still struggling with accomplishing a "softness" on the patches of moss that are not just decoration inside the grout. It might need just a high frequency noise added on top of all of it.
The first image is a close up of the worley noise. This made a really nice 2D shape and drives the colors but when turned into a displacement, it goes mountainous. I need to plateau the peaks or even better find a smoother version of it. I've already used a smooth SOP to balance out the edges of the displacement.
The second image is what I'm going for for the extra fine lumpities that moss has that give it the really soft looking texture. It seems that moss is a layer of fine lumps on top of larger lumps.
The third image is the second image added to a less frequent noise. However the large lumps do not match the color and are way to uniform. If I can combine this noise with the first worley noise, then add the fine noise on top, that should be a great combination.
