Hi,

a couple of month ago I switched from Maya to Houdini and so theres no day where I still miss basics :roll:

How get rid from the dark areas, this shaded artefacts. It seems to me that there is a problem with the normals after edited it with a transform SOP. Well, maybe I'm wrong. How to solve that?

Thanks in advance and

Cheers

check point normals and primitive normals direction.

Use Facet Sop with “post-compute normals” option
