Arnold AOV's

I am trying to move over from Mental Ray to Arnold.

 

I have always used passes from my renders to composite in After Effects.

I have worked out how to extract each pass in after effects with extractor but z depth not working or material ID's

 

Can anyone explain how to use a z-depth with Arnold AOV's in after effects. 

 

Also material ID's. For this I just want everything Black except the material I use for spot lights. 

 

There is very little information with regards to Arnold for use with 3ds Max. If I cant get this to work I will use V-ray in the future as there is way more info out there.

That's the tutorial I followed but didn't work from Max to after effects. z depth just shows as white and playing with setting does nothing. There is no way to control z-depth distance from what I can see either. 

 

Spent 1 day trying to do this. It was easy with Mental ray. 

 

Just spent half hour playing with V-ray and got all the passes I need without problem. Not impressed with Arnold speed either compared to other two engines.

The Z AOV isn't normalized. How did you normalize the values for viewing?

I have the same issue and haven't seen an answer. The AOV Z renders out a white image. I've tried rendering a Tiff and adjusting exposure but there is no information there. I finally downloaded the pool ball tutorial to try that and got the same blank white image out of z. Here's the tutorial if anyone can tell me how to get a workable Z depth image out of it.
