what cloud textures are you using?
im not sure but there is this option in the particles called “ShapeInOut”, just set it to “inAndOut”
That just determines if particles go outwards from the emitter or inwards or both.
the one on the left is rbxassetid://7216851225
is my favorite smoke texture, and fits pretty well with “clouds”.
im working on a fog for my game using the same method i used for the clouds, i will keep you updated if i find some new informations
what settings did you use for the left one?
