in this scene i've a big box wiht transmissive material and a medium node plugged in, and i get a nice volume fog effect.
Now i'd like to have it a density variation in volume so i plug a map in Medium but nothing happens.
To keep it simple i tried a check texture, which is B/W so effect should be strongly noticeable. If i apply the map to Volume Box's material we see it's correctly sized and placed:
so i would expect a visible effect on volumetrics but nothing happens, no matter where i plug the node.
Is there a way to texturize density/scattering ?
