Hi i am having trouble with my occlusion in maya 8.5 i can get occlusion to work when i do not have the wall geo in the scene but as soon as I put the walls in it only renders out a black screen. I have tried maya help to no effect

I'm no expert at Maya, but try reversing the normals on your wall/box, and see if that works. It may be the ambient light that the occlusion pass creates is not reflecting off the wall. Reversing the normals might work.

Delete the occlusion layer in Render Layers and create a new layer with all objects. I have similar problem very often. Make sure that all needed objects are included in the layer. However, trouble can be caused by something else:
- Not correct material
- Mental Ray doesn�t like subdivision surfaces. Try to convert them to polygon.

Can you take out your scene? I will try it on my maya.

When you created a new occlusion layer, a new material was assigned to all selected objects. You have to be sure that occlusion material is assigned to your wall.

Thanks mates. The whole scene is made of polygons. I downloaded some of the furniture from turbo squid and I made sure that it is all poly's baring the bankers lamp. It is working a lot better now but I feel it is slightly to dark.

Around you, to hold fast to you! I was obsessed with how, in your embrace. No one in a night, one more than the street, you put my mind to try the fragrance on your body quietly into my nostrils, into my Heart, but you also know nothing about when I have lost! Your lips are so soft, so I can not help but greedy, your body is so small Sophie ah, I did not dare to relax you, I am afraid, afraid of opening up after you will be blown away, so I forced in with you that I treasure! I have been intoxicated, had been secretly sucking your beauty, this is how I envy ah, let me also become part of your body now, as I always have you, will never be lonely! In this small world, you are my all, embrace you and I will have the entire world. "Cold?" Your words are so gentle, Do not you know, you are my sun, with you, I will be cold?
