Vray Ambient Occlusion HELP PLZ>>>>

[thenusiansivakumar]

HI

I am trying to render my first interior scene, I am facing a problem with Vray ambient occlusion rendering it is not rendering few objects in the scene such as walls, floors, curtain. I have attached my both rendered output with this thread. I used VRAY AMBIENT OCCLUSION 2.0 script to render this output. Plz help me to sort this problem.

 

Thx

Regards

 

Thenu

Why are you running a script to get an AO pass? Just put a VRayDirt map (which is an AO pass) in the VRayExtraTex render element, and tweak the radius/samples/etc and you'll get a perfect ambient occlusion pass out as a render element every time.

I second this!

Your wall normals are flipped. If your script is rendering this as a extra texture, then AO will only work on forward facing normals.

 

I also second Chris' reply. You should know what the script is doing, ie the AO process, before you use it. Scripts are nice but they aren't always necessary. They can over complicate a fairly simple process.
