vrimg channel not found...

V-Ray V-Ray for 3ds Max Issues

I’m having trouble converting a vrimg file with an embedded zdepth.

vrimg2exr filename.vrimg -info
returns…
File “filename.vrimg”:
resolution…
number of channels: 3
“RGB Color”; type: RGB Color; alias: Color
“Alpha”; type: RGB color; alias: Alpha
“VRayZDepth”; type: float; alias: Zdepth

So when I go to extract it…
vrimg2exr filename.vrimg filename.exr -channel “VRayZDepth”
returns…
Specified channel name “VRayZDepth” not found or channel is not a RGB channel in file…

I’ve never tried to extract channels from a vrimg. What am I doing wrong?

Thanks in advance…

You can only extract RGB channels in this way; the z-depth is a floating-point channel, so the converter does not know what to do with it.

Some compositing programs (like Nuke) can read these channels too though.
