Okay, AS. I meant the list of procedural textures that you have immediate access to. This is the list that you can get to by shift-clicking the title bar of the texture channel to get the icons, or regular clicking of the title bar to choose from a text-based list (boring). But the default Bryce textures that Bryce5 comes with (many of which are very tolerable textures) use many procedural textures that are not included in the above list. This is what I meant by additional textures that you don't have immediate access to. If you want to use them in another texture, you have to go into the DTE and save them. Screwy in my opinion. Dan, as for the algorithms, I think that the CAPABILITY should be included, whether you are intended to use it or not (apparently this is what happened with the entire DTE--note that this was a good thing to leave in). Some of us may be able to understand them enough to use them if someone explains it clearly enough to us, and some of us may not. That's not the point; the point is that it should be there. Fractals (I hear) can be very complex too--yet there is an entire community here at Renderosity dedicated to understanding and celebrating the math involved. Just my $.02
