heh heh heh.. I am still waiting for the random dot stereograms!! (just kidding)

anyway.. I wonder if setting your output window in the animation properties would change the render window size? either there or the render options..

try changing either..
"Animation->Animation Setup"
or..
"Render->Render Options"
...and see if that changes your output window size.

Also, FYI.. I think you are going to run into problems with the way Poser handles interactivity really soon now. Poser doesn't do the "remain on top and still let me click the camera" stuff very well if at ALL.. Just a sad but true fact.

I am out of my depth on this stuff, so I can't help. I can nit-pick some directory issues and then I pretty much have to step aside. I can tell you that saving to RAM instead of disk seems unlikely. The problem is that Poser only lets you do certain things, and if they aren't there.. well it's pretty tough if even possible to do them.

For example.. wouldn't you think it would be easy to create an AVI (movie) file using Poser python? It's NOT. You can create sequences of images, and you can create a flash movie (SWF), but you can't create an AVI. It isn't supported by the poser library.

So buffering images in RAM is pretty tough. But it doesn't hurt to ask, eh?
