papsphilip 8 Posted May 13 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 Share this post Link to post Share on other sites
papsphilip 8 Posted May 13 here is curvature compared to a custom wrangle solution. Almost there. The wrangle does almost what i want Any other ideas? Share this post Link to post Share on other sites
papsphilip 8 Posted May 13 curvature would be perfect if there was some kind of threshold. remapping curvature to 0-1 and ramping it doesn't change anything. Share this post Link to post Share on other sites
