Bake Wrangler
Does it work in blender version x?
Currently the long term support (LTS) version 2.9 and the what ever the current release version is are supported.
Can you add 'this' feature?
There is a good chance the answer is yes! If there is a feature you would really like to see, come to the https://blenderartists.org/t/bake-wrangler-node-based-baking-tool-set/ thread and discuss it.
How can I do 'this' or what does 'that' do?
First check out the documentation at bake-wrangler.readthedocs.io, also note that everything has a tool-tip if you mouse over it to try and explain the function. I have created examples in the documentation and will continue to add them as needed.
If you still can't figure it out, have a look at the https://blenderartists.org/t/bake-wrangler-node-based-baking-tool-set/ thread and post your question.
