The rocky-woody looking things, how to do them.

this is for enfusion.







I'll make the description general enough to work in any 3D app.

1. Create a plane. Make it roughly the ratio you'll want the finished wallpaper to be.

2. Using a "slice" type of tool, start making vertical cuts all the way across the plane. Try not to make them perfectly parallel, you're going for a detailed but not perfect kind of a look. Make as many as you can stand. Try to maintain a "flow", don't be totally random.

3. Repeat, except on the horizontal. You should have about ten minutes in so far. :)

4. This is the part that requires some "vision", but not much. Start extruding the polys you have just created in groups, try to be creative and do it in a way that mimics a natural kind of rock or wood-like formation. Keep going over and over the piece, extruding groups of polys. There will be temptation to give into complete randomness in your selections, resist. Try to avoid extruding the newly created polys (the sides).

5. Get some high res pictures of concrete, wood, dirt, etc. It's pretty easy to grab your digicam and find some dirt or rocks. :) Create a blend type material, stack all these organic textures up and play with the blending, use alpha maps, etc.

6. Create an appropriate grayscale bump map, easiest just to take one of your texture maps and desaturate it, bump the contrast up. It doesn't have be anything special, just something to give it a little texture and organic-ness.

7. Create spotlight. Turn on GI. Grab an hdr map if your rs supports it. Render, adjust, render, adjust, render, adjust until you're sick of yourself.

8. Finis.
