THE PLACE FOR ALL THINGS BRYCE - GOT A PROBLEM? YOU'VE COME TO THE RIGHT PLACE


Subject: Great trees, I need to know how to make them

Well, I have a vision of sorts, but I am going to be as secretive as possible about it till later (although im not surre why). I need to know how to create a extremely detailed tree... an absolutely gorgeous giant. I find myself outside my realm of knowledge (which is relatively small area) and could use all the help I can get. Thanks Tempest

Well, the only way to do it that I know of, is the way I do it. Lattices. In a paint program, design the tree in several parts. Start with the roots that go out from the bottom into the grass. Make it at least a 500 by 500 grayscale, Be as detailed as you want. Remember how lattices work and design accordingly. Paint with gray on black, not white, and apply some gaussian blur to it after you've finished. Design the tree trunk, the branches, etc in this way. create a lattice, then go into the terrain editor, click new, set your resultion to at least 510, 1040 is better, click from picture and import your gray scales. Then do that one by one for each part of the tree and position everything in Bryce to put the tree together. Use lowering to bring the height of the lattices down until the branches and such look round. It's complex, it takes a long time, and positioning is a pain, but it gets really good results if you put the time into it, and with the right materials mapped to it, it will look great. As per my piece Wizard's Tree. As far as foliage, you're on your own there, but you might try amorphium if you have it, to make some unusual, uneven foliage shapes rather than spheres. The texture mapping there is the real catch. Bryce still doesn't have diddley as far as decent foliage textures, but if you play with it and use foliage sparsely, but spread out in a somewhat realistic manner, it can look pretty fair

There are also some great tutorials here and over at 3D cafe.

I was thinking, and this is something you'd be better off asking Hawkfyr. I think it's possible, that you could create a lattice that would have the shape of a small bit of foliage you wanted, and then texture it with a foliage mat, then use multireplicate to spread it out around the branches. Hawk is the master of multirep, so I'm sure he'd go and try it and then tell you if it could be done. I'm thinking that might be a good way to get very detailed foliage.

Feel free to chirp in Hawk man, I could use some advice.

One other method is using the totally free app l-system-4 a tree and branch maker that uses genetic blueprints to re-create the recursive forms found in nature. I've built dozens of trees this way. They can be huge, too. But are generally controllable to smaller polygon counts. You need to follow a few basic written steps to get your design off the ground, but once learned it's simple to get a good dxf model that can be multi-replicated in bryce. Laurence Lapre's site on the web. Hope this helps.
