I am using Blender 2.82a (Cycles) to create a fuzzy ball. However I am getting this strange ring of artefacts in the rendered image, where the alpha channel shows through - I am not getting the smooth rendering that I expect. How can I fix this?
I have looked at Cause of Alpha or Black Artefacts in Render (2.79 - could not find the relevant setting in 2.82a. Also I am using volume scatter, not surface material)
