Hi,

I am recently frustrated with the noise of the SSAO. Please see the attached image. We have the same problem with the sample on the official site too. I played around with the parameters but nothing helped. I am wondering if it is a problem with the normal reconstruction from the depth buffer.

BTW, I tried SSAO2 too, the quality was really better but the performance was really poor compared to SSAO. And not all browsers support webgl2.0...

Any idea to improve this annoying noise stuff?

Thanks

Hey, according to this playground https://www.babylonjs-playground.com/?24 have you played with the falloff and base values ? The problem with "depth only" SSAO is that it is harder to configure :(

With the editor you can easily drag'n'drop your scene and take the perfect values: http://editor.babylonjs.com/v2/ . In the "Post-Processes" tool on the left, you can add the SSAO Rendering Pipeline and modify all these values to fit what you want

Hi Luaacro,

Hum...finally I integrated SAO (https://threejs.org/examples/webgl_postprocessing_sao.html) in my App.
