Hi, Thanks for your reply
The problem is i have a specific modelsheet to follow, with peculiar forms.
I know growFx could do the job, but needles need to blend is the form, not penetrate in it. Even if MetaMesh works pretty well, a retopolgy is needed afterwards.
And i would work with instances to save time and effort on Uv's, topology, and still modifying the picked instance.
Still searching...
