papsphilip Posted May 13, 2022 Share Posted May 13, 2022 Hi, i am trying to make a mask based on the relative flatness of my mesh or relative curvature? i am not sure how to put it. i have a rock with bumps everywhere obviously but you can clearly see areas where in general it is flat although there are small bumps, you can distinguish relatively flat surfaces by eye. i tried generating the curvature map and then blurring it but the results are not that good. They are soft after the blur and not precise. the other thing i tried is clustering by normal -6 clusters- for a box like projection if you will. but the problem with clustering is yuo have to decide the number of clusters. i would prefer a threshold of normal similarity. thats what i will try to do next Quote Link to comment Share on other sites More sharing options...
papsphilip Posted May 13, 2022 Author Share Posted May 13, 2022 here is curvature compared to a custom wrangle solution. Almost there. The wrangle does almost what i want Any other ideas? Quote Link to comment Share on other sites More sharing options...
papsphilip Posted May 13, 2022 Author Share Posted May 13, 2022 curvature would be perfect if there was some kind of threshold. remapping curvature to 0-1 and ramping it doesn't change anything. Quote Link to comment Share on other sites More sharing options...
