Hi, 1/ Sometimes when I am doing a plan the roof ends up "shiny" in areas and I have to move it around in 3D to get a decent shot of the house. Is there any reason it does this and how can I fix it? 2/ One side of my house in 3D is darker than the other so the renders end up looking really bright and beautiful on one side and much darker on the other, how do I fix this?
