Artifacts on backface of dirty translucent object
I have a mossy glass material applied to a cylinder. By default "Two sided" is unchecked and the material looks fine that way in general (see picture 1), but I would prefer to also see the moss on the backside of the glass. Checking "Two sided" allows me to do that, however I also get artifacts that look like parts of the backface are actually rendered in front of the front face (see picture 2). Has someone an idea how to get rid of them and why this happens in the first place?
