Output set, not outputting.

[duke2]

I'm using Vexus to set the separate channel output (which I think is the problem) and it's not actually outputting anything. Open the scene, hit render and watch it rip through frames without outputting anything! I know the actual output path won't exist for you, but it usually throws an I/O error if its attempting to write to an invalid location.

I'm using VRay 3.60.03/Max 2016

Weird, the output path appears in the UI but:
vr = renderers.current
vr.output_splitfilename == ""

Here's another file with output set, and it DOES print properly with the above script, but still no output. Note that the output path contains the character '#', however this hasn't posed a problem in the past.

Also note that so far, it works with EXR/VRay Raw output.

Hello,

For the raw output V-Ray writes the images so the file name is enough and it works.

For the separate render channel option - we still use the image saving functionality from Max. For it we need the file name and also a bitmap object with all the output format specific options. So you need vr.output_splitfilename set to some string with the filename but also vr.output_splitbitmap set to a valid Bitmap object.
As a quick workaround for some internal scripts I did the following:

...
vr.output_splitfilename = outName
tmpbm = Bitmap 10 10 fileName:outName
save tmpbm
vr.output_splitbitmap = tmpbm
...
max quick render
...
close tmpbm
free tmpbm

This creates a small (10x10) bitmap at the required location and then V-Ray will use the Bitmap object as a template to create the actual output files.

Best regards,
Yavor
