I’m very much a noob so please forgive me if this is a stupid question.
I’m want to apply a very high resolution displacement map to a UV Sphere. I could just subdivide to get the millions of faces needed but this seems a waste as I only need the extra faces in a relatively small proportion of the sphere. I could subdivide by hand, but I was wondering if there was a way to use an image to control the areas affected by a subdivision modifier? E.g. have white areas subdivide and leave black areas alone?
Thanks for any help!
