Ao glass

[MjTheHunter]

I'm sure this get's asked often, but I couldn't find a solution.

I want my AO to be visible through glass. I tried affecting the shadows in the refraction, also tried transparency in the dirt map, but nothing seems to work.


Thank you

Is it anything specific or just general AO pass? If general AO just hock up ur AO to extraTex in render layers and that should do it...

[MjTheHunter]

I would like to avoid render layers so I only have to render once.
The wierd thing is, that it's only a problem for some objects, and not others..

[Dariusz Makowski (Dadal)]

Sorry I mean Render Element. Put it in to ur ExtraTex texture slot and it will render at the same time as beauty and get u glass looking good if I'm not wrong.

[MjTheHunter]

I know how to set it up and all, that's not the problem.
The problem is, the AO only works for some objects and not others.

Humh...

I've attached scene with working effect. Also in dirt texture u can enable/disable work with transparency option to ignore glass from casting AO etc etc... Hope this works for you?

Um just re-read ur post... what other objects are not working with? It could not work if the materials were not Vray materials but blin/mr etc etc? Also are your normals correct? Make sure they facing the right way around...

[MjTheHunter]

That's the strange thing, the objects appear completely fine, also checked the normals.
I will post a screenshot of it tomorrow.

And material? Is it all Vray? Maybe they have overrides in extra attributes...

It might be useful to post a part of your scene for investigation.
