# Cloth and smoke simulation not working

So I was creating a smoke sim (in 2.82) and had a cloth fall onto the smoke to act as an obstacle, so that it would collide with the smoke, however it did not. I have set the cloth to be an effector but it won't move the smoke what so ever. What setting is there to help with this?

• Have you tried checking Is Planar and turning up the surface thickness? Feb 18 '20 at 4:06
• I did not do it before, it now works
