Hello!
I am having issues altering the materials of the sub regions I have made. When I click on a specific sub region, I am unable to click on the little button in the properties table that should allow me to change the material. It is grayed-out/unavailable for me to click on. Please let me know if you have a solution for this!
I've also attached the file for anyone to view.
P.S. I am a 5th-year Arch student with my semester final critiques at the end of the week so... any help ASAP would be great!!!
