You're welcome! I'm glad I could provide some useful info on your obps.

I haven't had a more detailed look at your textures yet. First of all: they're not that bad either, in my opinion. As a matter of fact, some of them are very, very nice indeed.

One thing I've noticed even with my little knowledge of the Bryce Material Editor and the DTE is that for some of your more complex textures you seem to have used many parameters that have no effect at all on the overall texture.

Example: The parameters in the VALUE section of the Material Editor. For most of them (if not all, I'm really not sure) there is an either/or relationship between the sliders and the dots you place in the colums of this section. That means that as soon as you place a dot in a column and thus control this slot through a texture source, the sliders have no effect anymore. It doesn't affect the texture in a negative way, it's just confusing when you enter the Material Editor and want to tweak a texture.

In some cases, dots were activated for the Bump which refer to the bump channel of texture sources that are, for example, plain gray and therefore will not produce a bump effect, no matter what setting you use for the slider. 

There also seem to be problems with some of your textures with regard to mapping and tiling, but an analysis of that goes way beyond what I know about procedural textures in Bryce, particularly since the DTE is involved in a number of those textures.

By the way, since you seem to be very fond of Bryce, and mat mad as well , you may find the following link of interest (it's not for the Material Editor, but the DTE). It's one of the best DTE tutorials in English I know of.

If you'd like to find out more about how the Material Editor (and everything else in Bryce) works, I recommend a book that should still be available. It's "Real World Bryce 4" by Susan Kitchens. Although there have been no updates for newer versions of Bryce, this book still applies to many aspects of current Bryce versions, in particular with respect to the Material Editor and the DTE. Some of the things I mentioned above are, as a matter of fact, things I have learned from that book. It is well worth the money, you won't find anything that compares to it because it explores the very depths of Bryce like no other documentation.

Sorry 'bout my lengthy monologue... I'm quite a big Bryce fan myself, although I have to admit that meanwhile I prefer programs like Vue for landscaping, and I've never really learned to use Bryce properly... but I'm still playing around with it from time to time.
