shadowdragonlord's right, there's no s/w on earth that can convert JPG to procedural (although it would be cool if there was!) I have Corel 9 texture creator (like the Bryce one, but with more channels) but of course I can't use it in Bryce unless I map the exported JPG as a static tex. In Bryce, you can either use the mat libraries for procs or the lst libraries for pictures. The only disadvantage is that they're in a different place, otherwise the effect is the same.
