I was following a tutorial below for real-time building destruction. Basically the building is made up of multiple different materials (glass, wood, concrete, etc.). Around 26:55, she isolates the glass panes from the rest of the structure. I did the same steps as her but I still see parts of the other structure. I need to find out how to isolate the glass part of the structure. Any help is greatly appreciated!
