fingers were made by extruding... but I did have a problem with Carrara when creating them... for some reason the vertex modeller duplicated all the vertices in the fingers and the knuckles. This resulted in a second layer that I couldn't see but would cause havoc anytime I tried to link or weld any vertices. I couldn't figure out the jump in polycount until I grabbed a vertex and pulled... the second layer came off like peeling off skin. Very strange... not sure what cause it and it hasn't happened again. I just hope it doen't happen to one of my high poly models!
