the last preview doesn't allow to dim the reflection intensity anymore like before. The option was not perfect in the past, the range to small some times (maybe 30%...100%), but now the intensity is much to high (maybe 90%...100%). The glass rack shows a tiny difference between 0% and 100% reflectivity. I hope it can be fixed since I think about to renew my license and work on the project again.
left last preview (current no active license) vs. last renderings during the project some days before.
