No worries - it's the user variables as created on the Yeti node, like described here - so basically it's like exposing graph internals to global attributes on the node. For example you can promote the "width" of a specific part of the graph to a user variable so it can still be tweaked upon. Giving you more granular control, even if there's a cache file already. The user variables are also described in the Yeti docs here

I have tested yeti with and without any user variable and all ayon actions works normally...

User being able to Load Manage and lastly Connect Yeti via action in the inventory. No issue were found also with older products published before this PR...

All good!

Here is my asset with user variable loaded and checked if present on the yetiRig asset. Works fine.

Actually @LiborBatek this may have been my bad in the testing notes. But they should load to the Yeti Cache product when loading - not just to the loaded yeti rig. So from that yeti rig in your screenshot, publish a cache - that cache should then also on load have the user variables.

Thanks to @BigRoy for noting I have to test also yeti cache product....

So it works fine and with propagating user variables.

Can be merged i guess...
