Z-Depth Render Element Problems

[CAPTURE_MM]

Hello,

we upgraded to Maya2014 with vray build: vray_adv_24501_maya2014_x64_23873

I encountered a problem with the zdepth render element, which doesn´t work like it did before.
See attached pictures for details.

Thanks in advance

Hi,

Could you share that you used? Could you expand a bit on what do you expect as correct here for your settings in each zdepth channel?

[CAPTURE_MM]

I´ll try to explain what I would expect from the zdepth channel in the images I posted before.
The scene just consists of some cubes WITHOUT any background object, image or something else
For the render element I used the mentioned values for the Depth.
Depth Clamp is ON and Filtering OFF

1st image: Depth Black 00 || Depth White 30
The Background should be white

2nd image: Depth Black 10 || Depth White 30
Looks OK

3rd image: Depth Black 30 || Depth White 00
Background should be black

4th image: Depth Black 30 || Depth White 10
Background should be black

5th image explains what it should look like with Depth Black 30 || Depth White 00


When using 0 neither for black or white something gets flipped internally I guess?
I hope you understand what I mean.

Masking the zdepth pass via the alpha from the Beauty in Compositing won´t work due to the fact that we don´t want to have anti-aliaising on the edges of the clipped objects.

Yes, thank you for the explanation. I thought that might be it, but I wanted to make sure. Seems like a bug. I'll try and get back to you with more info on when we can have this fixed.
