I too am having Rendering problems - the following is the message that appears - Error Message - Insufficient Disk Space to Render at Current Resolution This erratic problem started the middle of last week. Prior to that, I routinely rendered complex scenes with multiple figures at 2400 by 2400 at 300 dpi. Now, half the time, I can not render a single figure at 1600 by 1200 at 150 dpi without getting the Insufficient Disk Space message. About 80% of the time, the error message appears the other 20% of the time it renders correctly. It doesnt seem to matter whether I have just started a new session, have recently re-booted etc. There does nor seem to be any pattern to the problem. I have tried clearing the .INI file, re-installing Poser, and searching the registry. (Did not find any Poser entries in registry - ??) My network and tech guys have been over this computer and have not found any problems. All other applications work fine Im routinely editing other large >1 GB graphics files and videos without any problems. The machine is about a month old. We've tried Defrag as was suggested by Poser support and in the previous messages, but nothing has helped.
