Hi.
I'm currently working on a personal mod that, heavily based on your Colonize Unlimited, allows droids to colonize barren and frozen planets (and toxic).

As you suggested in comments, I took a look at your files at github which helped a lot. But I've hit a problem.

I added the option to colonize a planet easily, so mechanics wise the game does what I wanted it to.

However every tile on the 'new' planets are the default 'green hills' tiles, and terrain details just says
'pc_barren_tile

pc_barren_tile_desc'

Descriptions:
I haven't found out where or how to add the descriptions yet. Anyone happen to know what I need to do? I found the actual descriptions in the localisation folder at colonize_unlimited_tiles_l_english.yml - but I can't quite figure out how to apply them.

Graphics:
I added the dds files from Colonize Unlimited into the mod folder
gfx/interface/icons/tile_backgrounds ex: pc_barren_1.dds (up to 4) and same with
gfx/portraits/invironments ex: pc_barren_I01.dds (up to 4) as well as pc_barren_sky.dds

The files do not seem to work as intended as the barren planet portraits are just blacked out. Interestingly the vanilla pc_barren_sky.dds portrait seems to not work either so clearly the files are doing something. I also pulled toxic portrait by mistake, and the same issue with black screen occurred untill I renamed it, then I got vanilla toxic world portrait back.
Same applies to terrain tiles. The game is using the default so the ones I've put in seem to do something.

Any chance you guys have got the time to lend me a hand, or better yet, make a standalone version of Colonize Unlimited with nothing but 'unlocked' planets. As far as I can tell, no other mods have unlocked planets quite as well as you have.

In advance, thank you.
