Rounded edge by shader?

[Micha3D]

Hi,

if I understand right, the Octane rounded edge function is a mesh manipulation. Why not a shader based edge softening? I never used shader based edge softening. If I understand right it's based on ambient occlusion calculations. Maybe there are some reason why it is not implemented. Or is it on the way? My hope is to get smooth edges without the limits of mesh manipulated soft edges.

Ciao,
Micha

hi Micha, Octane's edge rounding is via a shader created at runtime. But for this to work, it requires the vertices of the geometric objects to be welded before applying the round edge value.

So, please try to add this feature for Rhino too. There is a note that the Rhino soft edge feature needs to be used, but it's not so stable working.

Rhino does not provide meshes with merged vertices, so the Octane round edges feature does not work. Instead, use the Rhino round edge feature.

I use a third party software for unfolding UV and this one needs welded edges. During export from Rhino I need to enable vertex welding "welded". For example this cause that I can export a complete welded (closed) mesh cube, but the edges are still sharp (not smoothed displayed). So, maybe you need to enable something for the export to Octane too.

The Octane plugin doesn't "export" the scene - it gets the raw geometry data directly from the Rhino API - so that is not an option - sorry.

Sounds like the McNeel team could help, since the functionality is there available. Or doe's the welded export to the standalone not work?

You are far better off using the Rhino round edges, since at the moment they work much better than the Octane round edges.
