Unable to loft



I’ve been trying to loft two different sections. When I try the “Solid.ByLoft” node i get this error:

“Warning: Solid.ByLoft operation failed.
Unable to loft! : BAD_UV_SKIN_DIR – Surface U and V derivatives are in the same or opposite direction.”

Did anyone knows why am I getting this error? erro1


Does Surface.ByLoft succeed?


Hi Zach Kron, thanks for your reply.

No, the "Surface.ByLoft " node gives me the exact same error…
