You can do all three in Bryce. Oddly enough, even the best tuts out there only tap the basics of the texture editor. Bump mapping is a Poser term I think (I'm new to Poser so forgive me if its used with other programs). Bryce has a slider in the main texture lab that lets you choose bump height, same thing. But that's just scratching the surface. You can go into the deep texture editor and choose any of the 3 screens that add/blend and click the B channel for bump height. And you can go deeper than that and open the noise slider and click on the upper left green button and change octives, fractal type, and mode. You can add, subract, blend, etc all three into the final procedural and if that's not enough, back in the main texture lab you can choose three additional procedural textures to blend in with it. In other words, you won't be bored at night. Altitude sensitive textures are also doable in Bryce. You should have a texture called highlands which is altitude sensitive. I made a variation of that to texture my donuts in the tut above. Been working on a snow top mountain (for some odd reason, Bryce snow textures like Bryce Classic put the snow at the base of the mountain). Flipping that around is not as easy as it looks and I'm still putzing. It is doable. Randomizing textures is easy enough, you can randomize bitmaps or procedurals. To randomize your procedurals, click on the upper right down arrow in the three view texture box in the basic editor screen. You'll get a box with several catagories. Pick a category and you'll get a ton of textures to choose from. Or, you can go into the deep texture editor and click on the lower right button for any of the four windows shown. Remember, you can click on the way the three upper windows link and interact and change that too. Also, you can go in the deep texture editor to the filter and put in a number of different preset fractal equasions or enter your own. There's a lot of undocumented features in the DTE and many more I can't begin to explain in this reply. Guys like Doc Mojo who wrote part of Bryce have gone on to make programs like MojoWorld which take fractal math in 3d images to a whole new level. I've never seen a decent tech manual on the DTE and wish someone would write one. I don't even know if Corel understans what they bought from MetaC. The link above is a tut on making donuts in a freeware program. The texture is an altitude sensitive variation I made from one of the terrain procedurals. I think the original was Highlands. When you get a chance, and when he gets his server back up, Brycetech has the best DTE tutorial available. www.brycetech.com
