Hi, so i am new to twinmotion and i am using layers for materials from rhino so that i could then easily transfer the materials to Twinmotion (glass is blue, wood is purple, etc). However when i place the model in twin motion, the majority of the blue items (glass) are transfered but some of them are left as the material of the wall. this is very frustrating and i cant seem to find the answer. I appreciate if someone could help.

glass windows are blue.

only left window is glass, the other is considered as a wall.
