"2. Renders go into never never land with infinite loading texture message. No dump. No error handling. No time out. Nothing. No way to go through and check geometry etc to see what went wrong." I have yet to encounter this problem personally in P6, but I don't use extremely large textures so that may be why. There is now an option to keep textures loaded into memory (as well as shadow maps), so that after the first initial test render, it doesn't subsequently need to keep loading them for every render thereafter. Apparently, there is a memory issue, which CL is aware of, and has acknowledged they will fix in a service release. That might clear up some of your problems.
