I have a scene in 4.15 using realtime lighting / GI and DFAO / ray-traced distance field soft shadows. In these screenshots you can see the Mesh Field visualisation and the DFAO visualisation. This is basically the interior of a small cube room, with windows on either side. As you can see from the DFAO vis. there are square artifacts along the flat surface; yet the mesh field vis. doesn’t show and obvious reason why this would be the case. I should also mention that the exterior of this part doesn’t show these artifacts.
The mesh is already using quite a high DF scale, and checking ‘generate DFAO as if two sided’ didn’t help. Project scalability is set to epic; and DFAO for the most part works everywhere else, it’s just the interior I’m having troubles with. Any tips on improving the quality of DFAO in interiors would be welcome.
