At the start I have this strange situation:
(I got this by playing with a model and dragging around faces with shift+ctrl combos)
There are 4 edges that have a crease, but it seems that also the 4 vertexes have an “additional info” to be sharp.
Those 4 edges are in the same place of the control object!
… it would be useful to be able to do this intentionally! But it’s impossible!
All the other edges don’t have crease.
If i remove the crease and re-add it, the shape is different:
subD_bug.3dm (69.7 KB)
Is this expected this way?
What are the info stored in a SubD object?
I thought SubD were like a meshes: vertexes, faces, edges (that can be “welded” or not).
The fact i was able to export this deformation tell me there is some other additional information stored on SubD objects.
Can we know what and why? Knowing it might result in deeper use of them.
PS it would be cool to have edges that start smooth and end with crease, not only on/off for the whole edge.
