Bumping this thread because I've spent two hours trying to figure out why I cannot get a decent AO pass out of an exterior scene I'm supposed to wrap up so I can fully concentrate on current and more significant projects.
Why was this element removed? I've used Corona Lightmtl and such successfully many times to do AO passes (and anyone about to tell me AO shouldn't be used, don't, since it's not up for you to decide) but with this current scene it's just not working no matter how I set it up. And it's not only this one, I sometimes need to spend an unnecessary amount of time to get it right.
It would be really good to have a reliable element where you could just specify the radius and render out two or three different sized AO elements because like it or not those passes are crucial not for ME but for the people who pay me. The client doesn't give a shit about physically correct contact shadows, they demand certain things of the picture they've ordered and that should be the end of it, give them a 100cm radius AO pass multiplied over a box primitive if that is what they pay us for.
So pretty please, tell me it's there somewhere and I just can't find it or just add it back and save us time :)
