I have tried to plug a Geometry > Pointiness node then a Color Ramp to the Emissive input of the Metallic shader in the latest build at the time i am posting and nothing appears, i get a flat color.
It's a bit too early for this I think, there's lots of Cycles features that Eevee does not support yet. But will leave it to the Eevee developers to decide if they want to keep this open as a to do item.
Indeed, it's still early for this kind of report. Technically the bug is that we are exposing nodes that are not supported. But pointless is one of many. Closing it for now. Thanks for the report though.
Really needing this node to work for true procedural texturing with EEvEE.
Am a game developer and am waiting for this soo much. When I can bake stuff with this feature I maybe could even move away from Substance.
This or a dedicated curvature/edge wear node
Idea: if eevee cannot support pointiness, is it possible to design an auto baking step (like global illum step) so that a cycles-rendered pointiness map gets auto created for use in Eevee. I guess 'in theory' this could be a plugin too, although it would be better to get a solution into blender core. This is basically what other people are doing manually get get pointiness in Eevee by doing a manual baking step from Cycles... but it's a lot of manual steps if you have several materials that use pointiness.
