//OpenSubDiv// only works if there are no more modifier below it in the stack that manipulate the mesh.
So if I for example use the //Subsurf modifier// with //OpenSubDiv// turned on and then use the //Wireframe modifier// on the output, //OpenSubDiv// doesn't smooth the animation anymore.
But when I turn off the //OpenSubDiv// in the// Subsurf modifier// again and in addition use **a second //Subsurf modifier// after** the //Wireframe Modifier// and turn on //OpenSubDiv// on that one then it works fine.
To have the same visual result like without this second //Subsurf modifier//, I set it to Simple instead of Catmull-Clark.
The problem is that my mesh now has a massive plus of vertices (vertices that are really not necessary!) and it only works when I let the modifier subdivide my mesh at least once.
Is it possible to change the option of 0 subdivisions on the //Subsurf modifier //so that //OpenSubDiv// still works?
