I've got a new little tool for quickly converting models into seamlessly tiling textures in just a couple clicks. Introducing ProPal.

I built the tool for designing tiling textures like building facades, roads, walls, columns, etc. It tiles only in U or V seamlessly. It also controls most common RTT parameters directly at the object level (and in the Projection modifier via a custom attribute) so you don't have to click Add + dimensions for each render element--instead just set one dimension and check/uncheck the elements you want.
Sorry about the video--I was recording on the fly and should have set the object with more resolution and pushed the Projection cage to create a nicer normal (as in the image above) but alas I have almost half a dozen kids who keep my brain sufficiently frazzled to excuse such mistakes. For those who buy ProPal, the scene in the graphic is available to download as a sample scene.
The tool is on sale for $4 through Sunday. Then goes up some.
