BlendSrf - wrong shape direction

Hi there,
I’ve got a prob with blending srf. first shape is ok, next is wrong direction.
srf was made with networksrf. problematic is shaping border (wich contains from networksrf both U and V direktion) to a scaled copy of itself.

Hi Julian - My guess is the surface UVs come together at that location where the shape goes the ‘wrong’ way - please post your model and someone can take a look.
