For the example file meshdist_volume.ma, how do you scale up the effect while maintaining the same look? Or even relatively close. It disappears once I scale it any larger than 2. and I can't seem to find the settings to bring it back viable to edit the texture, if I want to scale it to say 10.

Thanks a lot,

-Dave

You have only applied the mesh distance nad volume shader and not a texture?
Then it should not disappear if you scale it larger. (it would disappear if you scale it down, but that can be compensated with the global density of the volume shader).

Wihout the mesh distance and only the volume shader attached, you get the right behavior?
(larger object, more opacity)

no, Basically I just opened the example file. I'm not sure if I only applied the mesh distance and volume shader and not a texture? The example file has a texture and uses the mesh distance but in an unusual way to me. It has a second object as what appears to be a max size. What I want is any object scalable editable and still get the same fall off (or at least relative fall off per scale).

The example uses one object as hull for the volume rendering.
And then a second smaller object for the density of the volume rendered.
The denisty is then modified with a fractal.

It would be possible to do it with only one object, but then the fractal can only carve density away to the inner.
And not get bigger than the mesh distance object like in the example.
