Most Skyrim SE mods will work. The following types of mods are the ones you need to look out for. - SKSE based mods; Some of these mods have VR versions as an optional file. - Animation mods; FNIS works in VR but it's tricky to get it to work. - UI mods; Generally unsafe, unless specifically for VR. - Utility mods - ENB (VR ENB has less features than regular SE ENB) - Perk mods/overhauls. They need to be specifically made for VR, I think. Everything else (weapons, armour, quests, npcs, locations, cities, mesh/texture replacers, etc.) should work fine, provided they don't have anything in the above.
