The basic setup is, Maya 2008, rendering out Depth pass with the depth box checked on the renderable cameras in the common tag. The frame buffer is 32x4 RGBA.
Before it worked. Then, this one nuke render crashed on me (after rendering out 200 frames or so, reading everything correctly) and when I restarted nuke, all the .EXR depth files are recognised as having RGBA channels (the color bars say so, even though these channels have no information) and it does not recognise my Depth channel anymore.
Edit: The error is: the file is not a .exr file.
Current work-around: Mass-renaming each depth files into .iff works.
But it used to work on .exr...
Does anyone have this problem?
