Houdini 20.0 Nodes Geometry nodes

Labs Edge Color geometry node

Color sharp edges on geometry

Edge Color will highlight sharp changes in geometry, with control over contrast and blur. It also lets you identify convex vs concave edges, and treat them seperately.

Note that it requires as reasonable amount of subdivision between the required edges. The color is stored as a @Cd point attribute, so if there isn’t enough internal detail per flat region, there won’t be enough points to isolate the edges from the rest of the geometry.
