So I went to try RNDR today. I'm stopped short before I even get started. The file uploads on the website seem to be broken. This is also true for ORC. They just hang at 0 bytes for 30+ minutes on a 1Gig file (and my network activity is near zero%). I did have success going to ORC from within the Octane app, but can't get a file into RNDR via the web upload. (Or any other means.)
Hope someone has some insight on this.
