I'm not sure exactly what error message you got when trying to do large renders. Here's the one I'd received in the past. It goes something like this: "Insufficient disk space to render at this resolution." I think that was only experienced with Windows 2000 Pro and Windows XP. The solution for that problem (for me) was to install Poser on its own 30GB hard drive. Hey Poser is the biggest application on my computer anyway... I rarely get that error message any more, and the solution to that problem now is to defrag the hard drive. **** You can operate Poser in one screen resolution, but you can also render in a new window. This allows your final render to be larger than what is allowed for your screen resolution. I did that all the time before I got a larger monitor. Have you done your renders in a new window? **** It's hard to properly diagnose your problem without knowing the full extent of the symptoms or the error messages you may have received. You might just need to defrag your hard drive. That's one thing many "artist-types" forget to do! Of course, I'm both a techie and artist. *** Don't be hard on yourself. You're not stupid. And remember one great purpose of this community is to share information. Besides, I'm still befuddled by some of the simplest things.
