Hard Edges

Hi
I was looking for a way to mark/group edges and make them hard in terms of smoothing and this is what I came up with:

I couldn't find a standard way to do this. Maybe an edge option in the Normal node would be cool.

Cheers

here's mine...it maybe clunky..but it does use only whatever 'standard' nodes avail...

Actually, I just tried simply plugging in your scene to an edgecusp (skipping the subnet) and it works...am I missing something really obvious ?

OK, a bit clearer now...I'm selecting faces/prims while you're selecting edges...so you could be trying to 'crease' some single line rather than a closed loop from some faces....still, once you've got the lines I'm  puzzled why you don't just feed it straight into an edgecusp ?

Hi Noobini, because I want to persever the geometry. I just want to have Hard Edges based on marking and Edge Cusp opens the geometry, which you can see by simply plugging a Point Jitter with a small amount after it, the mesh opens, I want the same exact mesh but with hard edges.

Cheers

no my question is why bother with the subnet ? after you've selected the edges...why not plug them straight into edgecusp ? why overcomplicate thing with the subnet ?

Edge Cusp opens the mesh. Now, the scene I've uploaded first did not have the subnet output the proper node (Attribute VOP) so the sense of it might have been lost. Sorry about that.
OP scene file fixed.

I just noticed though that while you can't set the normals on edges, you can use a group of edges... So there's that.... x)


Edge Group > Set on Vertices with 0 threshold!

Eh!

ahhhh that's why I was puzzled....couldn't see the point when your sphere was still being split (with jitter)

yeah so now if I put display flag on the attribvop, your sphere doesn't get split anymore....thanks for pointing out.

And I noticed Facet opens up a mesh as well....hmm.....
