GTAO pass not working with alpha maps and transparent background

[metaltwister]

Hi.
Seems like the the GTAO pass does not process the alpha channel.
I noticed that the alpha map support is already mentioned in the "Future Work".
Can you please help with where to look to add alpha support?

If you want to support partially transparent materials I recommend rendering the transparent objects after performing the AO pass. If you want to support alpha clip you'll need to add support to the shader variants in the pass.

Thanks for pointing towards it. I'm looking to add support for alpha clip in materials and also support the transparent html background. Right now the background is rendered as black and the html background color only appears when the rendering is disabled for TAA.
I tried turning the transparent boolean to true for all the 4 shader material variants in the pass. But seems it didn't work. I'll look into the GTAOshader.
