Hi All,

My new 3D Artist is having trouble removing the dirt look from the walls in his first model. Does anyone have any suggestions that could help us please?

Such “dirt”, being a result of high noise in lightmaps, may occur in draft quality bakes. How many samples (Bake tab) did you use for this bake? For the final quality we advise to use 800.
