Pixar repeating textures

Postby joepal » Tue Feb 28, 2017 12:24 pm

Pixar have released 130 repeating textures used in films. They seem to include normal maps and bump maps. There are some cloth fabrics in there which look useful:

A few test where texture scale is set to 15. Here we can also see why it would be useful to have a homogenous mesh density in uv unwrapping when working with repeating textures (breast area and skirt area obviously have very different mesh densities for the female formal asset).

The "dimd" texture (found in the "paper" category) actually looked kind of cool on a dress...

Nice! always on the hunt for free seamless textures! wish they were at least 1024x1024 but im sure ill find uses for most of these

Cool. I will have to try these textures.

This might be fixable. I just played around with a node setup to generate homogenous uv-coordinates from object coordinates.

The main idea came from my old friend Pythagoras. u=sqrt (x²+y²), v=z. Problem: Your texture gets mirrorred on the x- and y-axis. To avoid this you have to give your 3D coordinates an offset. You'll have to play around with the values. The 2D uv-coordinates get scaled afterwards.

This is not perfect. You'll always have a region on your object that looks terrible, but it might be good enough to bake your uv islands seperately using different offsets. This is what my panties from the user repo look like with a uv grid and the above node setup.

That looks very useful.

Maybe we should have a section in the docs about clothes texturing, where stuff such as this and the mindfront/punkduck tutorials could end up.
