I got the following set-up:
Now, I don’t know how I could possibly convert all of that into a square-resolution image. How could I do it?
Truly, I have no idea what you mean… you show a sphere, but you say you want a square? Seems like you want a plane instead of a sphere?
No no, the sphere mesh is a reference to see how the gradients mix together. Is it possible to export those gradients (essentially the texture/shader, not sure) as an image? Or, just export the whole thing as an FBX?
Put a square orthographic camera directly above that plane and render it, save the rendered image
Well that’s one way to do it. Thanks!
For a simple square you might try to bake it…
