Hello to all, this is my first post :0)

I seem to have discovered something in 12.5.469 that may be of use to others: Using Pyro shelf to create smoke creates a fluid source node with a source attribute for density that is highlighted green, when seen from the Scalar Volumes tab, whereas creating the same effect manually does not. This value (by default in manual setup) seems to affect the overall look of the smoke giving a more mushroom-like look. You may not want this look and find it as difficult to change as I did.

A work around is simply to choose fuel from the container settings tab pull down menu and then choose smoke. Now the attribute will be set correctly i.e., will be highlighted green like the shelf tool and the result will be as expected.

Cheers,
Daniel
