Hi, first i dont know if this is the right section to post this in, if not sorry to my question Whats best BSP and Static mesh because when i add too many BSP they go invisible so i convert them to Static mesh but then when i fix the light map resolution to a wall for example the outdoor side looks good but then the inside is to bright or the other way around and it takes so long time to render with mesh. so what is best to do?
