Fair question! The reason it is not covered in the docs because the new docs are work in progress. Also we discovered a nasty bug in the Submit from 3dsMax feature after the last update. The issue is that Render Manager won’t care if the file has changes in it and it won’t save a copy of it as it should, instead it will just take the last saved version and submit it. This will cause unexpected problems.
We are working on a fix and will release a new version soon.
Regarding the options:
- Submit Render Job to RM will submit your scene as it is, it can be a single image or an animation
- Submit Local DR Job to RM is a V-Ray only feature where your computer will be the master and the render nodes will join you
- Submit DR Job to RM is also a V-Ray only thing, and it will create a simple DR job
You can try them out but make sure to save your file first
