Reindeer the node based render manager for 3dsMax is FREE to use during 2022 and probably longer.
Reindeer has been used for many years on lots of projects. It's a flexible tool not just for rendering. Use it for automating rendering or simulations or storing scene specific scripts in the scene file. Check out videos at the following link:

It is free for the time being (possibly forever), due to the costs of making it commercial being higher than the revenue (classic lose-lose).
