Materials: Can't change density in volume

Support Materials and Textures

Nothing happens when I try to change the density in volume. I need to set it clear down to 0 for smoke simulation. When I try to render it, blender locks up and I have to force it to close.

Is this a known issue? I did not see anything in here about it.

I’m using blender 2.62 on win7

Was it crashing before you set the density to zero?

3

no it wasn’t. it’s only after the density is changed.

Okay, I downloaded the latest version of Blender and that fixed the problem
