Hi,
Hi, I was making a building, and one half of it was square, while the other side had one big rounded edge, and I needed to subsurf the rounded bit only, is it possible to select a few vertices and subsurf them alone? If not, is there a way around this?
It is hard to suggest how you should approach this without knowing what you have in your mind. But here is basic approach. Make the round part first; if you are using subsurf, apply it so you have real mesh to work with. Remove the faces where flat surface comes out, and just extrude those edges out to form flat side of building.
Here I made the round part of building from cylinder. And extruded flat side of building out and filled in the roof:
You could always split your object and on one half remove the subsurf modifier (modifiers are always applied to objects and not mesh). After applying the subsurf modifier on the other part you can join them again.
The subsivision surface modifer can’t affect part of a mesh yet, but you can use Edge Crease to affect how much selected edges are affected by it.
Select an edge an press Shift-E to add a crease.
Crease values range from 0 (completely affected) to 1 (completely unaffected).
Keep in mind that since this operation is additive, if you’ve already set one or more edge to a crease value of 1, to remove that you have to input -1.
The Mark Sharp flag doesn’t affect the subsurf modifier.
