V2 update: Praised be the shiftupgods, thanks to the photo mode a consistent Tachy model could be done. Use "StellarTachy" for her character and "TachySuit" for the outfit (which can fit other characters too). There's a third tag called "BossTachy" for her bossfight version, but it sucks and it's handled pretty poorly because of the assymetrical design of the mechanical wings, tentacle arm and stuff, so I'm not even listing it as an activation tag.
Recommended weight: 0.8-1. Should work well with realistic and 2D models, Clothing pretty straightfoward, if some elements are missing like the small "led lights" on the suit, try using the "science fiction" tag. Like, share your pics or buzz up, the more it makes, more Stellar Blade LoRAs I can bring.
