View Full Version : indirect illumination with ao (render element) question

02 February 2012, 03:57 PM

I am having an issue while rendering:

"mr A&D Xtra Diffuse Indirect Illumination with AO"

as some of the elements appear full black and I am wondering why as in the beauty render they look ok?

-Also as a side question I have some issues with the glass "windows" as they get far from the camera some aliasing issues occur. My render settings for antialiasing are set to
4-16 mitchell with jitter turned on. Also using Max trace depth at 10 (5refl, 5refr)
The windows have those indents actually modeled so its a straight physical glass shader on them.

This is the raw render:
edit: higher res (

and this the "mr A&D Xtra Diffuse Indirect Illumination with AO" where you can see the black objects..

Hope you can give me an idea, thanks in advanced.

Have you checked which way the normals are facing on those objects? They may be reversed.

Hello Tim,

I took a look at the normals and they looked ok. But then I tried simply recreating the same shader but with a new one and then applying it to the objects and it worked ok. I am not sure why this happens as the shader I recreate was exactly the same.

I think it might have something to do with the fact that I merged all the objects into my lighting scene. There might be some bug/error while merging both scenes, hence why some materials were behaving bizarrely.

Thanks for your time.
