multiple render camera supports for 3dsmax

[moonyuet]

Changelog Description

Supports for rendering with multiple cameras in 3dsmax

• Add Batch Render Layers functions
• Rewrite lib.rendersetting and lib.renderproduct
• Add multi-camera options in creator.
• Collector with batch render-layer when multi-camera enabled.
• Add instance plugin for saving scene files with different cameras respectively by using subprocess
• Refactor submit_max_deadline
• Check with metadata.json in submit publish job

Additional info

• If we raise the errors differently for running subprocesses to 3dsmaxbatch.exe or 3dsmax.exe, it will error out. So currently the way to find the error is different from what we did in maya.
• User won't use published workfile to render but instead they use the camera scene files stored in the {project}/{project_name} folder
• The temp camera scene files are not supported yet.

Testing notes:

1. Create Render Instance with multiple cameras selection enabled
   

2. Add the camera you wanted to render into container
   

3. Publish

4. It will creates different camera files and submit to the deadline with multiple job and plugin infos.

5. Once the rendering is finished, it will include videos with different cameras.

@LiborBatek I restored the code with the original subset name setup, can you please check again?
If it is not working, I guess it could be some other issues regarding to the submit publish job update.

[LiborBatek]

Unfortunately still broken...when inspecting the Publish folder for sequences...

Note the weird name of the publish folder (highlighted one)

and actual files

Secondary render camera completely missing in publish too...

Even tho the work renders are ok and done:

@LiborBatek can you test this again if you have time to do so? It seems working in my side now where publish folders have shown the folders and outputs correctly.

[LiborBatek]

All working now! I have tested with Arnold and everything working perfectly...

two rendered sequences produced from Camera01 and Camera02 both correctly published into publish folders and with proper naming.

And published rendered sequences in correct locations:

I can also say that I have successfully tested also in Redshift for max. So it works well in both renderers without any issues!

And both for max2023 and max2024

Overall great news!!

@antirotor can you take a look at the code again? I didn't use the loop function you suggested as I tested it with Maya, and the subset name doesn't include the AOVs as expected. Thanks!

I've started rewritting few things to f-string as a suggestions here but then I've realized it is on more places. I know, cosmetics, but at least with the longer strings like:

renderlayer.outputFilename = "{0}_{1}..{2}".format(
    output, cam, img_fmt)

it is much more easy to read:

renderlayer.outputFilename = f"{output}_{cam}..{img_fmt}"

Otherwise it looks good!
