Yeah,I had unrawped all mesh’s uv,if I see a very small part of my scene it looks very good.Skyligt and directional light makes shandow not so real.I’m thinking that DFAO may be not suit for out door building or there are something wrong with my meshes.
And the version of my engine is 4.8.2 . Also I colse my editor when DFAO is on, It will crush down. I don’t knwo why.T_T
