Some great filters there Stephen Ray. Here's a great site that has been mentioned before, but there are always new folks coming to the Bryce Forum. Craquelure 3D Freeware-Updated to ver. 1.35, An extremely useful plug-in for generating both techno and organic textures. Has a terrific "brick" filter that is scalable, and one preset that looks like alien sanskrit. Great for heightmaps too! Water Ripples Freeware- great little filter for what else? Water ripples. Lattice Composer Freeware -The classic plugin that spawned a tutorial and I believe a monthly Bryce challenge. Great for making textures or heightmaps, and a lot of fun. Jama 3D Freeware- kind of a ripply filter-I used it to make a corrugated metal texture. Seamless Workshop- A filter for making seamless textures. All these are available for free download at http://redfieldplugins.com/
