    when I apply AO in Blender it looks ok.
    When I publish the scene in verge the AO looks very noisy and feels like pixelated . as seen in the image.
    Is there any way we can make it smoother or less noisy by adjusting any setting in Blender or Verge ?

    Another option: Bake your AO map separately. Use your photo editor or denoiser and smooth out the AO map….put it back into blender and bake out a new set of maps?

    Oh ok
    so these are the only options.
    I thought there could be something in V3D to tweak it.

    Well.. the first method described by solid is the same option as baking out your own AO….the addon is just doing some of it for you.

    Verges dynamic AO – SSAO – ScreenSpace AO is the second option.

    If your project can handle the noise and your clients is okay with it…then all is good.

    Otherwise….bake and sprite sheets for the win.

    If you are talking about dynamic AO try to play with this parameter
    app.postprocessing.gtaoGenerator.precision = 0.25
    It’s set to 0.25 by default. Set it to 3-5 or even more to get less noisy effect.

    You can tweak this value in Blender but from 0 to 1 only (not enough)

    Puzzles and JS. Fast and expensive.

    If you don’t see the meaning in something it primarily means that you just don’t see it but not the absence of meaning at all.

    Hi
    yes conventional method is one way.
    I feel Evee’s AO is better which is GTAO.

    as of now client doesnt have any concern on it. They accept it. But I just think of improving on it.

    I checked the parameter script but it results in brighter or a darker output instead of minimizing the AO noise spot sizes. check the image attached

    Under Blender’s AO settings I can increase the factor even beyond 1 which further darkens the effect of AO. But unfortunately, Blender doesn’t allow to increase the value of trace precision beyond 1.

    When increasing the “Trace precision” value you should decrease the “Factor” and “Distance” values. That should be a balanced combination of parameters.

    I also tried this larger settings to check.

    it looks like that it gives screen space AO effect. look at the floor behind pipes. a slight view change makes it noticeably light & dark where it has to be constant.
    Is this something Verge 3d might fix in near future? or is it a EVEE artifact issue?

    the attached screen recorded video shows how the AO darkness artifact is seen behind those pipes. on panning one attempt it shows darker while slight more panning show lighter
