do you use occlusion

[jadhav333]

So do you render the scene with GI, lights etc first... then overlay the AO over that?

 

Thats how I understood it and tried the other day anyway

 

But if we had to render with GI in the first place, what speed beenfit would we get? since rendering with GI as it is is time consuming..

 

I thought. we just do a plain render with out GI as a beauty pass. and then blend the AO pass over it in Photoshop, to simulate the GI effect without GI

yes exactly

 

 

yeah the whole point is you dont need to have any GI as were faking it with AO.

 

it does work with physical camera also. just remember to turn off exposure in the camera settings and also the colour mapping needs to be left at defaults as any tweaks in there will have an effect on the image.

It can be used with or without GI pass. The GI pass can be a lower quality and blended with the AO pass, therefore gaining speed.

Or you can use the Vray AO plugin...

works great...and easy

 

i installed this, launched it, and hit render, but my image looks like it did when i rendered it normally. .....maybe i am missing something.??

once you open the AO plugin from your Tools dropdown you hit the "render" button on it's panel, not the normal render button....
