So we already have mods like Grey Wardens of Ferelden or the Unofficial Remaster that use model ports from DAI to DAO.
And right now the only things missing for a complete DAI experience is the DAI chantry robes!
The only mod that tries to achieve this is the Viva la Orlais mod, which has UTC files for npcs but doesn't work properly. all of the outfits are distorts from a distance
(I think the models are missing proper LOD2 files or at least that what I figured after downloading the mod and trying it out)
If someone with more knowledge than me can help fix those models (like making LOD2 files for tham? not sure how that works) and utcs- i would be forever grateful!
