I'm following the "Making Realistic Dust trail" question which is not accurate for today blender smoke sim interface.
I try to reproduce this answer for cgslav but in blender 2.9 which does not have the same interface for smoke sim. After discussing the most accurate question would be: How to replicate the 2.82 worflow described later on the pasge to Mantaflow?
Is that possible? I tried on my side and did not succeed at all. I would love to understand how to translate this method.
Original answer from @CGSLAV
Create emitter with Real World Scale - this is important, as Smoke sim can differ based on scale. Mine has ~56x7m. Apply Scale!
Add to it Quick Smoke - F3 > Quick Smoke.
Scale Domain in Edit Mode to make it as big as you need.
In Domain settings I've changed only Resolution - 192, Temp. Diff. - -0.04, Adaptive Domain - checked and High Resolution - checked + Resolution Division > 2.
5.Collision Object. This is most important thing to do here. Set it as Smoke > Collision and Animated.
- Now you have 3 options how to interact with smoke.
- Allow object to "sink" into smoke.
- Attach to object "plow" to raise smoke and not be visible in Render.
- Attach Force Field to object to "suck" smoke from the ground.
