Hello guys, I tried adding a postprocess antialiasing filter according to the docs but it makes my canvas go black? Am I missing something? Simply adding this line var postProcess = new BABYLON.FxaaPostProcess("fxaa", 1.0, camera); makes it fully black.
Does this PG work for you? - Babylon.js Playground
A repro in a playground would really help indeed 
I am wondering if there are some weird incompatibilities or if it is device specific.
