"Domain Type" and other options not showing (new to blender) I'm trying to change my domain type from smoke to gas, however my smoke domain settings are completely different from the tutorial I'm watching and I'm not sure how to change them.
Fluid/Smoke settings have changed depending on the version of the Blender.
If your smoke/fluid settings are different than a tutorial, get the exact version, the tutorial is using.
You can download any (even the oldest) version of Blender on their download page.
