When r_radiosity is set to 1, OpenSpades renderer does large scale ambient occlusion. This takes more blocks in account than the [default ambient occlusion](Simple Ambient Occluson) does, making itself more suitable to simulate the shadow of sky light.

Computation is done in CPU in background, and the computation result is streamed to VRAM.

Requirement

  • Requires 16MB of VRAM.
  • CPU must be fast enough to compute the ambient occlusion reasonably fast.
