Hi, I am making a house and have made, much of it, but I am hoving some problems. I have the same material for all the roof, but the color is not the same, here is a link to a screenshot of it:
It’s your lightmap, make sure the whole roof is one mesh, and don’t use a 2-sided mesh if you need to have the roof visible on inside and outside, if that’s the case then you need a thick mesh with a top and bottom surface.
