For anyone looking to still utilize these portraits, Strive version 0.14.3 broke most of MDM Mods from Squarich (linked above). You can still use Exposure, I just removed the other 2 mods and left Exposure in the Mods directory (if you leave the other 2 mods in the Mods directory, it will cause constant errors even if they aren't enabled). For whatever reason, the name of the directory for Exposure is actually "expanded_portraits", even though it's called Exposure in-game. Hope that helps.
