Hi there @roland,
I’m still working on this subject (of R&R, reflection, refraction, glass, metal, etc…)here or there;) hope you are too?
Lately did set-up a preview environment for my 3D commerce scene sketching/evaluation, released under the sexy name;) of ‘Project Chair’. You can find it here:
There is a big part on reflection (glass, metal and textile) in the sketch. I’m trying to give both a base and a freedom for others to experience. I would need to add more variants of materials/types, though… There’s a table with a glass made from a simple standard texture (no baking, probe or anything…at this very moment), but then may be you still want to have a look at it. Else, have a great day,
