[SOLVED]Why Doesn't Gravity Affect Smoke Density?


Atom

Recommended Posts

I create a sphere then click on Billowy Smoke.

I disable noise on the fluid source node so I get an even smooth volume sphere.

I dive into the DOP network and set buoyancy lift to zero and turn off all shaping.

At this point when I simulate, nothing happens, no forces are disturbing my density sphere.

But shouldn't the smoke fall to the floor? There is a gravity node present.

Do I have to somehow add mass to density to get gravity to affect it?
