Here's a closeup rendering using the simple "leaning tower" Bryce object that comes with the "Pisa" materials I've posted to Free Stuff. This rendering uses the hi-rez version of the material, though a lo-rez version of the mat (more practical for distant objects) is also included. The object is a grouping of three tall, concentric cylinders. The innermost cylinder has an opaque texture applied, while the outer two have the hi-rez Pisa material applied. My attempt was to make a material that would easily apply a "Romanesque" look to simple Bryce objects.

Very nicely done! Am on my way to check it out. manowar

One thing to keep in mind when using Bryce materials, is that they are essentially 2D in nature. So when seen edge-on, all the bumpmapping in the word still looks like a thin line. Careful choices in use -- and especially some postproduction -- are nearly always required.
