Color by UV Coordinates, UDK

Xenier

I was wondering if UDK has built in functionality to determine the UV coordinates of a mesh. For instance, I have a plane with four quadrants, each quad's UV's are in the corresponding quadrant of the UV grid (top right in the 1,1 space, bottom right in the 1,-1 space etc.). With those coordinates in mind, I now want the multiply my greyscale texture by a color with the end result being all UV's in the 1,1 space being red, 1,-1 being blue, etc. Any thoughts on how to make this happen?

Make your own material and use the texture coordinate node. It'll give you the UVs per-pixel and you can use clamp nodes or if nodes to turn these values into colours.

I'm curious as to why you would want to do this, because I couldn't come up with a good reason for it.

I went off and attempted it, and I'm sure there is a more efficient way to do this but it's a bit late.
My plane is as you described, not segmented but it ranges from -1,-1 to 1,1.

well, the idea would be to have one mesh, with a greyscale diffuse that gets colored through the shader, the colors being R,G and B were just for simplicity

so the solution you have here has the colors determining the UV coordinates, how would I use these to determine the UV's but apply my own colors to each section?

nevermind, got it! Thank you so much!
