Quote - What version of Bryce? There are still some un-resolved issues with image importing in V. 7-7.1 pro. The application crashes out etc etc. as far as size limitations I don't think that was ever clear as far as I know, but you really don't need super high rez images for light gels etc etc, "most" of the time 72 dpi or 150 dpi images work great and are less taxing on your CPU.

 

Sorry for the delayed rely. Somehow I missed yours:

I'm using Bryce 7 Pro. I guess the gel size would seem to be more a matter of the total number of pixels rather than the dpi, because there are no inches in virtual space....
