Is it possible to get two Voronoi textures, F1 and F2, to use consistent colors for points?

So let's simplify your idea a little bit, and look at some raw-er data: Same voronoi, top and bottom. Top is F2 distance - F1 distance. I've marked some centers roughly with empties so we can keep ...

Two identical node setups produce different results

You didn't pack the texture image, but we can see at a glance that your shape has very different UV coordinates than his: These UV coordinates are going to be used to read the texture. Different UV ...

How to increase precision of color ramp affecting model?

It is a known issue, ColorRamp marker positions are rounded to the next higher multiple of 1/256, leading to unexpected output, especially when set to 'Constant' interpolation. There is nothing you ...

XOR node for edge matte

There is not an exclusive-or (Xor) function in shader nodes; but you can synthesize an Xor using two nodes. Here is a very contrived example of this: and here is a plane that demonstrates the result:...

Map to influence light speed

I think you're asking about changing the threshold of cell shading. In which case, yes, you can modulate that with a texture. The precise things you'd do would depend on how you're cell shading. Let'...
