@Rampa how are you? I am currently having trouble with the Iray plugin after the new update. I remember you had a troubleshooting technique for the registry. What was it again? I l;iterally had an issue with the CCBasics plugin and had to re-download everything from CC2,CC3,CC3 Pipeline (and now the update) in that order just to get things working again. Only thing is now after all that, the Iray Plugin is failing. I have a few posts going in the
Official Character Creator 3.3 Issues Thread if you don't mind taking a look. There's someone else in there with the very same issue I had at 1st. Thanks in advance.
