poo... what video card are you using? Bryce does not like ATI cards (for one) and several others cause really wierd crap like you are mentioning here... the only partial fix that I have found is to download the latest updates to the drivers for your video card AND download the latest dll patches from www.microsoft.com for the particular OS you are using (I assume you use either win95 or win98) also look next to the clock..count the number of things you see there...if you can, turn off as many as you can (right click and exit or disable)..things like norton repeated insist on grabbing the processor and if Bryce has it, it isnt pretty (Bryce doesnt play well with its friends). you can also do other things to make ram come back...for instance, reduce the resolution of your monitor or even cut it down to 256 display mode (bryce will still render the 36million color image) then simply reset everything back to the way you like it when the image finishes. I have scenes that require me to do this or they would never finish...images that take 6 or 7 days to render...and these eat ram, processor, and cause windows to lose track of dll's necessary for display and even mouse movement. good luck oh, and I never "render to disk" ;) BT
