think you'd need to preprocess the mesh and encode the per vertex ratio of uv density to spatial density in say a vertex alpha channel. not sure on the best method to compute this but off the top of my head I'd say.... <area of all faces used by the vert >/<area of all map faces used by the vert>
Thanks, Yeah thats a bit sad, I guess ill go with a combination of using mesh data to change tiling based on need, and a fixed houdini setup. Are you sure we couldnt calculate the uv offset of vertex 0 and vertex 1 as example and compared it to world offset of the same vertexes (assuming a perfectly projection with no…
