Hey! First time poster and im getting into cascade 
I have a bit of a problem with artefacts on a simple smoke puff im building, it’s just a simple round mesh that i made a particle from. Now if you see the image i posted, the particle shows a blacker rectangle on the top of each smoke cloud.
It’s somehow linked to the mesh, i can get the rectangle to rotate by adding a rotation in Cascade. The material is just one node, particle color.
Has anyone seen this befour?
Thanks in advance!
