Just wondered if someone could help me?
I’m trying to get the darker sections of the rough stone to follow the dips and creases of the edges to my mesh as see in screen 2. Does someone know how to do this? I’ve tried using geometry node set to pointiness and tried creating a weighted normal and setting the geometry node to true normal but with no avail.
Does the pointiness really not work? You might need to pass it through a color ramp and do some searious tweaking to make it even noticeable (try to temporarily plug the result into the material’s color to better see what you are doing).
If pointiness really doesn’t work, you could try pass an ambient occlusion node set to “inside” through a color ramp instead. Just note that the number of samples on the AO will determine how finely a color ramp can modify it. If you go with this method, you will probably want to bake the end result, because it’s quite heavy on performance.
Finally, there is also the bevel edge detect trick.
