Hi all,
I am trying to render simple scene with AOVs (Arbitrary Output Variables).
I am rendering using the python command bpy.ops.render.render(write_still=True)
But I don't get any AOV in my output directory.
I did disable the auto brightness in the tonemapper and yet no output
What could be the problem?
LuxCore does not output AOVs

Please upload a testscene that allows developers to reproduce the problem, and attach some images.

Re: LuxCore does not output AOVs
The AOVs are available as Blender passes.
You can save them like you would in Blender:
Either you save the image as "multilayer EXR", this includes all Blender passes (however only very few programs can read this format, one of them is Blender).
Or you make a little compositing setup where you route the AOVs into a file output node: https://docs.blender.org/manual/en/dev/ ... /file.html
Note that the interesting options of the file output node are only visible in the properties panel (N-panel) in the node editor.
I think this is the same procedure as in Cycles, or am I wrong?
Example attached.

Re: LuxCore does not output AOVs
Thanks for the fast and detailed answer.
I am not a blender expert in blender so I am not sure about cycles.
I open .exr files with python opencv

Re: LuxCore does not output AOVs
Am testing AOVs a bit & i have a question... How or Where are settings for AO & Depth (Z-Depth)?
Re: LuxCore does not output AOVs
There is no Ambient Occlusion in LuxCore.
What do you mean with "Settings for Depth"?
The Depth AOV contains the distance from the camera in meters.
There are no settings to adjust.

Re: LuxCore does not output AOVs
Ah, OK.
Was assuming it's uses technique where start and end can be defined or by Camera clipping or Scene Box... yup, infinitely deep Z-Depth sounds nonsense
But works fine, alike in Cycles.
Thank you.
Re: LuxCore does not output AOVs
You can always multiply, add, subtract, ... the output of the Depth AOV with Blender compositing nodes if you need to rescale it.
