Uhm ... I installed this new release and there's no nodes displaying with octane materials created? In fact if I try to do someething in a node view etc, it crashes.
This however MIGHT be because I have a specific file I always load to create the Startupfile ... maybe it didn't like that older file.
Tested it .. if I load older files (also work), it will crash and not display nodes ... if I use factory settings, I get nodes.
