I don’t think it’s an issue with the material, here’s what I think would be the relevant params for the door and the vent, if you need to see more say so
another example against a similar door texture using the light switch, pipes, and button props, showing that non dark metal props such as the switch also appear dark

When I import models like the vent or vending machine into my godot project, they seem to be lit very darkly, even though they have similar material properties to models I’ve made that are lit fine, how would I fix this?
