Surface curvature not working as expected?

[ioioiofilip]

Is there a viable solution to get a nice curvature texture map in Vray for Blender without resorting to baking in Substance or Cycles for that matter?

I tried both Dirt and Curvature node with same issues: All edges that are not on a perfectly flat surface are taken into account for some reason. I remember the Max version did not have this issue afaik
