View Full Version : Adding ramp to density attribute of volume fog

12 December 2011, 04:43 PM
Hi all,

I've created a volume primitive and added a volume fog material to it.

I want to make the density of the fog gradually change from the top of the volume primitive to the bottom. When I add a ramp material to the density attribute of the fog material and then change the ramp so that it has black at one end and white at the other, it doesn't seem to affect the density.

Shouldn't this setup cause the density to change from 100% to 0% from one end of the primitive to the other end?
