I am trying to replicate a dark field photography setup for glass. Similar to this:
The final goal is to get a set of clean reflections on a transparent background that I can composite with the separately rendered content for the glass later.
However I get all sorts of transmission and reflection artefacts, that do not appear in real photographs with similar light setups. Especially the middle segment, which is completely without reflections in the reference is bugging me out.
I tried to separate the gloss and transmission rays in the blender compositor, but without success.
I think it is a problem with my glass shader, but I am out of ideas what settings to tweak. The setup looks like this at the moment:
Any help is greatly appreciated!
