Max: Multi-camera workflow for rendering

[moonyuet]

Changelog Description

This PR is to clean up the validation plugins for the unnecessary check on the camera name and update the correct directory for 3dsmaxbatch.exe so that it can be used in both 3dsmax 2026 and 2027.

Testing notes:

1. Create Render with multicamera option enabled
2. Publish

[LiborBatek]

I was able to publish a multicamera render from max while using RShift renderer...

It was also succesfully rendered on DL but fails on DL publish job which is on stale due to missing dependencies of rendered frames...

Here are the rendered staging files:

while the publish job expects different ones:

Im enclosing json metadata too:

maxrenderMain_metadata.json.txt

And publish report if needed:

max-RS-publish-report-260730-12-27.json.txt

[moonyuet]

@LiborBatek should be fixed with 7a0abf1

[LiborBatek]

Now all renders but fails due to still some discrepancies in metadata.json which Im also enclosing...

The publish job properties /dependencies looks good tho...

Some small excerpt from the metadata (see the full json below)

And the metadata json:

maxrenderMain_metadata.json.txt

Here is full publish report if need be:

It is more a fix on the twin PR of this in deadline.

@LiborBatek if it is working for non vray renders, please also approve this as the branch from vray merging to this branch, thanks

[LiborBatek]

As Im testing now with RShift...there seems to be an issue with separator as it expects different one...

Here is my staging folder with rendered frames using underscore separator while DL publish job expects dots..

Here is my ayon-3dsmax render settings for your inspection too...

And lastly the metadata json:

maxrenderMulti_metadata.json.txt

And I will also test the Arnold renderer....to see how it performs for it...

@moonyuet Im getting publishing error while trying to submit with Arnold from 3dsmax

Here is a full json publish report for you:

Arnold-multi-publish-report-260805-12-57.json.txt

P.S. I have followed very much same testing steps as for e.g. Vray and RShift and also freshly re-created the render publish instance too

Can you test along with the latest commit in ynput/ayon-deadline#231 ?

[LiborBatek]

I have tried two distinct scenes and double checked my pulled branches for ayon-3dsmax and ayon-deadline but Im still getting error while trying to publish the render from the max host...
