This has some not present in:

R2R THU Libraries from 2019.03.07 - 2019.11.02 + the TH-U.v1.1.7-R2R-2020.03.06

What i did was to copy the "...\AppData\Roaming\TH-U\Rig Models\" folder, uninstall the R2R, then install this.

Then I copied the "...\AppData\Roaming\TH-U\Rig Models\" folder again.

Then I useds those two as sources. I created folders for the "loose" rig presets, and now I have a fairly up-to-date Rig presets folder.

I zipped that up to save for future installs.

The IR folders seem like the same thing, but I did not bother checking.

I actually uninstalled this and reinstalled the R2R.v1.1.7.

If R2R fails to release an update after a while I may update with this, but I tend to stick with whichever team I have installed unless there's a good reason to switch.
