Multisub material on particles from object elements


Hello friends,
as the title suggest - I cant figure, how correctly add multiSub material to particles generated from object elements (generated by birth group). Base mesh has elements with 2 material IDs, but in pflow I only get one material ID per particle. Is there some solution, that the pflow will respect material IDs from elements ?

Solved: I just needed to add multiSub material to the base mesh which is used by birthGroup.
