Whenever I load into my map I find that the main spawn room door frame disappears and leaves an error. I'm not sure how to fix this so I have some images below to represent it. It reads: Detail prop model models/props_gameplay/door_slide_large_frame.mdl is using vertex-lit materials! It must use unlit materials! Detail prop model models/props_gameplay/door_slide_large.mdl is using vertex-lit materials! It must use unlit materials! They are different models as I tried to use different ones I found to see if that fixed it.
