Hi, is there a simple way I can invert a black and white texture with puzzles, so I don’t need to have an extra texture loaded in the scene?

Thanks!

Hi @kagoshi,
This is easy to do. Add an invert node to your shader on the diffuse channel. Tie a value node to its factor input. A value of 0 will leave your pattern unaffected. A value of 1 will invert it.
Values node can be set from puzzles. In my example, clicking on the sphere causes the puzzles to set the invert value to 1.

Ah, I’m using Maya, not sure a node with a factor value exists

@kogoshi, as long as the Maya version has a value node and math nodes, you can do this. The math is easy. I will assume that Maya uses a 0…1 scale for values.
1. Get a value from the puzzles. The value must be 1 or 0. O indicates no-change. 1 indicates inversion.
2. Subtract the diffuse value from the inversion value.
3. Take the absolute value.

Here is the node set up in Blender.

In Maya you can inverse colors with reverse node. We’re going to support it (as well as many other Maya utitily nodes) in the upcoming Verge3D pre-release.
