Okay here I will go through and list the many potential sources from where we could pull units:
-BarebonesWars/Vlad's Mod - I've never looked into these mods but I know they have a lot of new units. I guess it would be worth a look. Editing would more than likely need to take place to fit the mod.
-Casus Belli - Has some very good looking units. We could use some. Small edits needed mainly faces.
-Classical Age Total War - So many units and good models. Would need extensive editing because their textures are not the greatest.
-Diadochi Total War/Extended Greek Mod/Extended Cultures/Rome Total History - A lot of new and historic units. A lot of them retain the vanilla look, would only require new uniform color schemes to fit our mod.
-Europa Barbarorum - Tons of historical units, but they have a unique style that doesn't necessarily fit RTR. Would need simple edits
-Fall of the Republic Rise of the Empire - Has perfect units for RTR, maybe some small edits needed.
-Iberia Total War - Old looking units. Would need to be upgraded to fit RTR
-Paeninsula Italica - Great looking units, but models seem to look smaller than regular units?
-Res Bellicae - Would need a link to the mod before I could find out. Looks interesting
-Res Gestae - Has some interesting units for certain factions made by Prometheus. They look similar to EB's units. Would need editing.
-Roma Surrectum - Has some good choices for RTR.
-Roma Surrectum 2 - If we used any of their units they would need to be edited. A completely different look than RTR. I don't plan on using them.
- RTRVII - RTR but would still need edits on some units especially faces.
- AqD's RTR - Would need to be edited. They all have a blue/grey color scheme and are too shiny.
- Ancient Empires Elysium - Mainly Roman Units. A lot different look compared to what I am wanting.
- RTR Platinum Edition/Mini-Mods and Add ons - A gold mine for units to use
-Unused RTR units - Great source from RTR 7 and units that never made it in. I have access to these files as well as the RTR dev forum so I will have to compile the ones I like.
-SPQR Total War - Has a few interesting units especially for eastern troops.
-Ferres/Milner/Algaman - Great models, would need new textures, especially for faces.
-Macedon Expansion/Barbarians Revenge - Same as XGM and XC, historical but vanilla. Would need new color schemes. Russian mods.
- Rise of Empire - Chinese mod, similar to XGM and XC. Would need new color schemes.
-webbird, warspite, Kali - Already using their units haha
- Other Contributors - Augustus21's Phalangites, The units from the unreleased Punic Total War, LaCa's Units, Hannibal Smith's Carthaginians, Halie Satanus' troops and more. Most would require edits.
As you can see just about every unit ever made could be included. However, a good majority of them would have to be edited enough to fit the mod, which is why I am really needing someone who can work on textures.
