[Bf-committers] No more subsurf and mirror modifier with scupt mode?

[Ronan Zeegers]

Hello Sergey,

Why not keeping the old approach for the subsurf and mirror modifier? 
Like you said, at least supporting some simple cases.
The intuitiveness of this approach seems to be subjective.

To defend the old behavior, I think that a 3D artist know that he is 
scuplting/moving vertex of the base mesh. Not the "virtual" vertex of 
the subsurf/mirrored/displaced mesh.
It never disturbed me to not moving the shape because I was not clicking 
in an area where there was vertex.

cheers,

Ronan Zeegers
