I'm pulling my hair here. Seems that no matter which (closed) surface I attempt to create with MOI it comes out creased..... I know I can make more profiles and create a sweep which produces cleaner results but sometimes that requires a lot more work.
Do my curves have to be laser perfect?? What am I doing wrong?

In this example I'm trying to create the "hood"(top piece) of that mouse, and I want to achieve that by using a network.
(The hood high above the rest of the model is created with Rhino for comparison's sake)

P.S I also used the V2 version which also generates creases.
