I’m experimenting with the shader editor to extend how Grant colours the dinosaur scene mountains.
Here are 3 unit squares, each with a vertex at the origin. One in the xy plane, one in yz and one in xz.
The shader should generate a colour where the amount of red equals the value of the x coordinate, green the y and blue the z.
Although the resulting colours look similar to what I’d expect, the colour at the origin seems wrong. At (0,0,0) I’d expect the colour to be black. If check that by changing the Combine Color node to receive (0,0,0)
the cube does indeed go black.
Anyone know why my material doesn’t work as expected?
