  • Ambient occlusion as gbuffer pass

    topic says it all. I think its obvious to have ao as a pass.
    Thanks.

      in the newer builds we have renderelement integration and all elements can have custom settings...but it would rise rendertimes and possibly need a re-render in order to work i assume...vlado?

        I can't see a way to calculate an AO pass without calculating it :P
        It WOULD take more time.
        I assume Morbid Angel meant to be able to render it as a pass.
        On the other hand, with a replacement mat, it should be a one click pass already...

          yes, but when I go to render elements and select 10 pases to output, I shouldnt have to make a separate scene just for ao.

            So all you'd ask is basically that you have a check for an AO pass, and VRay does the material override bit for you?
            If that's the case, I am not sure i can script passes, but i might give it a go :P
            Notwithstanding the fact that i have no AO material with 47.03, i can try and see if it allows for the same operation with a standard vray material.

              well another part of the equation would be that i'd like to see it included as a renderelement because that would allow it to be included as an openexr layer instead of an extra file.

                Pardon me, but what app would you use to extract a custom layer off an EXR?
                This baffles me.
                Afaik one has to write a channel Writer to store it, and then plug a reader into some application to extract that.

                What am i missing?

                  Nuke?

                  Combustion needs support for exr channels! Exr sounds better than rpf, i mean i like the order of the letters the most.

                      aaaaaw!
                      I didn't know that.

                      So basically i just need, herm, let's see...
                      Price undicsclosed.
                      Good.
                      Cheap shit

                      I *think* for the time being i'd rather save an added file (exr, why not:P) for the AO pass

                      Even though, i admit, version 4.5 looks pukka. I sat through a custom demo of an earlier versio (2?) a few years back, and that made me half laugh and half cringe...
                      Seems working with the big boys does marvels to developement.
