Hey guys,

i need your expertise


What is the fastest way, to put lines exactly onto the surface of a 3d object with MoI 3d ?

Is there any solution ?

Attached you can find a smiley, which "flows" over a cone.. The aim is, to put the smiley exactly onto the cone,

which means that the lines must be bend in the right angle. I tried many stuff, but it is like impossible for me :)

Thank you for your help in advance !
