In Optinest 3, there is no material separation happening at import. With Optinest 2 the program separates parts by material and then optimizes separately each type of material/color.
Optinest 3 is putting all parts together, even if they are of different color/material/thickness which is an issue as we cannot identify which materials we send to the CNC.
Can you please explain or refer us to the logic of how Optinest 3 is supposed to handle the different materials so separation occurs properly at optimization time.
