So i’m trying to use the curve brushes to insert some tubes on top of my mesh, but it seems like the meshes are inverted/flipped inside out; when I smooth the mesh, it grows big, and when I use inflate, it inflates inward. the base mesh works fine with all the brushes, so I don’t think that’s the problem. Anyone know why this is happening?
Sounds like you have Zsub on instead of Zadd.
nope. That’s the first thing I checked. it doesn’t matter if I have zsub or zadd, it does the same thing.
edit: freakin restart fixed it. 
now i wonder if it was some option i accidentally turned on at some point. thanks for your reply.
