Curvature using hitpoint info

[Egert_Kanep]

I used subdivision modifier and applied it at 2 levels of subdivision

[B.Y.O.B.]

I may have found the problem: this suzanne model has apparently a LOT of duplicate vertices.

@B.Y.O.B. I receive a mesh with 6531 duplicated vertices out of 36494 but if I do a "mesh => clena up => merge vertices by distance", Blender tells me there are no duplicates. What is going on ? Is it the result of some applied modifier

You mean they are duplicate in LuxCore?
Maybe the Blender -> LuxCore conversion function is screwing something up (I rewrote it for Blender 2.80)?

May be, I'm not sure but if I look for duplicated vertices in the Suzanne, I found thousands of them.

Dade/B.Y.O.B , could you try this scene? I used different method to subdivide the object and it seems to give better results. Instead of applying subdivision modifer I subdivided object in edit mode

Yes, the "wrong" Suzanne has 3357 duplicate vertices over 10496 while the "right" has only 355 over 8076. Pointiness, to work well, needs a uniform surface, duplicate vertices cause "seams".

Maybe this is a bug in blender, exporting object as obj and then importing back seemed to fix this as well.

Pointiness shape is now able to handle duplicate/similar vertices like if they were the same. This a rendering with old Pointiness:

and this with the new one:

[Egert_Kanep]

Awesome, so now it doesn't matter if mesh is a bit wonky

Yup.

Great, thanks.
