Hi,
I'm trying some procedures to edgecusp but keeping point fused.

In Softimage I can use the hard edges,for that and it's very convenient


What I've tried:

- Use the Normal SOP like “3dsmax Smoothing Groups” making edges vertex normal Cusped.
It's totally unproductive

- Do edgegroup of “hard edges”, edgeCusp this group in a branch add normals, then transfert back the vertex Normals back to the original model.
Doing that is ok, but I can't really see what's going on

I'm thinking I'm missing a crucial option somewhere or a simple “EdgeCusp Vertex Normal” SOP…
Any Idea ?

If you have a group of hard edges, put that in the Normal SOP's group field, and then set the Cusp Angle to zero. All of those edges will get cusped, and the edges outside the group will be smoothly interpolated. Is that what you're looking for?

duhhh, yup that was it
