There were new versions of Substance Painter and Designer released just now, and their bakers now have a new “Match by Sub-Meshes Name” option.
Here is an add-on that will allow you to set up such a pair of names with one click:

More info on the linked page.
Nice, I’ll use it, thanks 
The add-on now takes modifiers into consideration when determining which of the selected objects is the high-poly, and which is the low-poly.
Please redownload and reinstall. Also, report any problems.
i was doing some baking and needed and found this little gem! I got it before and forgot but was reminded when i tried to donate. Anyways I found a small nuance that might be easy for you to fix.
Update:
Added a toggle to Baking Namepair Creator called “Also Rename Datablock”, on by default. This will also rename mesh data, since it seems it’s sometimes used instead of Object name.
Redownloadif you want it, and be sure to report any bugs.
Hope I understood your problem correctly : )
Thanks! Little stuff like this goes a long way.
Possible feature?
Sword_high.hilt, Sword_high.Rivet1 Sword_high.Pummel -> Sword_low AKA
Sword_high.001,Sword_high.002,Sword_high.003 -> Sword_low
This is with the assumption that any name based baker would ignore characters after the suffix
any change to get this working with blender 2.81 and 2.82?
This seems to work, the gumroad one wasn’t up to date thanks!
Doesn’t seem to work with Blender 3.0
For those interested in a fix for 3.0:
Here is the updated script

Select the lowpoly and highpoly objects, and press the Create Baking Namepair button in the Relations tab. The suffixes _high and _low are added automatically based on the vertex count. The name of the low poly object is used as the new name’s base.

can you post the updated .py file of it? Not sure what to do with the wall of code
Doesn’t work in my case, could you update .py?
bumb anyone able to make this addon work blender 3.0? And share .py file?
Here’s a version for Blender 3.0 - https://raw.githubusercontent.com/PLyczkowski/Baking-Namepair-Creator/master/baking_namepair_creator_3_0.py
(The add-on’s panel is in the ‘Bake’ category now)
Thank you this addon is a MUST HAVE in game development it saves tons of time, lets keep it alive!
Awesome! Love you <3
Fix commited for py changes in 3.1.2. https://raw.githubusercontent.com/PLyczkowski/Baking-Namepair-Creator/master/baking_namepair_creator_3_0.py
Hello there sir, i got question about this awesome addon. Is it possible to add automatic detection pairs of low and high meshes? Someting like perform AABB bounding box intersection between meshes?
