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....

Quote - Not sure exactly what you mean.

When a gel is applied to a light, an image may be loaded by the user to overlay across the gel. That image has an x and y resolution. I think that Bryce is limited in the size of the picture it can use within a gel. That's what I'm asking about. Images can also be applied to objects other than lights and gels. I guess the resolution limit (if one exists) might be the same. Is all this clear? 

I just bought Bryce 6. Very dissappointed in the broken materials animation "feature", which was not disclosed in Daz's ads. I'm boycotting Daz until they fix this.
