Any idea on how to get some type of AO between the meshes? I'm able to get some AO without raytracing (1st picture) but once Ray Tracing is enable it's no more (2nd picture)... Most of the assets on the render are textured with a trimsheet.
AO is a simple (not physically accurate) rendering technique that will darken any surfaces that are near to other surfaces. AO typically produces something closer to a dirt effect than a realistic lighting effect. In ray-tracing mode, global illumination is used instead - this accurately simulates how light bounces from…
