0.8.11

Ambient occlusion. One attribute on <tosi-b3d>, off by default. Checked flat; always (the in-headset setting) is not yet verified per eye on a device, and this release is partly so that it can be.

Added

• Ambient occlusion: <tosi-b3d ssao>. off (default), auto (on where the device tier affords it), on, or always. auto and on are flat-only; always also runs in a headset, for hardware that can pay. ssaoStrength and ssaoRadius tune the look; samples and resolution come from the device budget (PerfBudgets.ssao, ssaoSamples, ssaoRatio). Corners, stacked crates and the foot of a wall get darker, which is most of what makes simple geometry look placed rather than pasted. Measured on an M5 Max: about +1.2 ms a frame at 1344x640, scaling with pixel count. The depth-and-normals pass is built at the SSAO's own resolution, which measured 40% cheaper than Babylon's default with no visible difference. Sky, water, cloud deck, terrain and skinned characters all checked clean. New page: Effects → Ambient occlusion, with a small scene to test in a headset.
