RMG is a beast of its own which I don't care to tackle right now while there is so much else to do.
A few years ago I dabbled into making a Market of Time plugin and instructed RMG to generate some of them. The code is probably still somewhere on my old repository.
Since Creature Banks is already an existing RMG template, there might be little or a lot of work needed.

Indeed, indeed... this is my 3rd or 4th major rewrite of Unleashed code... I'd say I'm 50% through with this one so there is light at the end of the tunnel.

BASE contains all the files to run H3Unleashed as a standalone.
LATEST update contains incremental files compared to most recent BASE.

If LATEST update is older than BASE, then one should update both, otherwise LATEST is sufficient.
Last I looked, the other link in OP was older than 1.22; that version brought in the Battlefield Explorer which needs a few extra PCX and DEF to work correctly. I'll make a ERA-lod with minimal assets.
