Mixing a tiling texture with a unique texture?

Will Faucher

Hey,
I was thinking of testing something out for a tree I am working on, and I'm not quite sure how I'm going to make this work out. Here's the thing:
I want to have a tiling bark texture along the trunk of my tree. However, I would like the base of the tree to have it's own unique texture (To add moss, dirt, roots, etc.) I'm trying to figure out how I would cover up the seam it would create however. I can't simply paint over the texture in Zbrush/mudbox, since the upper part is a tiling texture. Here is a picture explaining what I mean. (Note, the bark texture is just a simple tiling texture I slapped on.)



Any help is appreciated!

Shouldn't be too tough. Just make sure the top uv's of your unique texture is flat, than make the top portion of that blend with the bottom of your tiler and so on. You'll probably only be able to do a tiler in one direction, unless your unique actually tiles a bit around the trunk.

You could have 2 separate meshes, the lower truck would be slightly larger and overlap the top trunk about 2 feet. Then on the lower trunk texture you have it be transparent in the last 2 feet so that it would blend into the top trunk. I think that would work, but there's probably a better way.

way too expensive, just use vertex colours to blend between the two

*Facepalm* Why didn't I think of that. Any other options? I just want to know for future reference if anything comes up.

I'd use a Gradient Ramp Map to blend them...3 different Map Channels (one for the tiling map, one for the unique texture and one planar for the gradient)...Mix Maps or a Blend Material...
