 From:  gui

Hi,
I am very new to 3D, and I must say that after a week of trying A LOT of different softwares, MoI is definetely my favorite =)
Using the Deform Flow tool (projection mode + rigid option), I have unexpected result :



So the elements are forming a circle, and when projected on a sphere, they form some kind of round squarrish shape...
Is it normal ? If yes, how could I get a "circular" result ?

Thank you !
