SE is yet to update the skeletons in old custom faces, and this leads to some Struggles TM in most current posing tools (especially ana and ktisis). I couldn't figure out a way to not make monstrosities happen, so I made myself a quick and dirty fix:
This is the crystal part from Exarch's uncovered face (face 203) pasted onto the new dawntrail G'raha face model (205) with weights added. Intended purely for posing reasons.
To use when posing:
1. Load in Exarch's data in your preferred way
2. Change the face model from 203 to 205.
Note: Since this changes DT G'raha, you'll not want this one to be active when posing him. I also recommend not having it on your default collection in penumbra.
The crystal might clip in more extreme cases!
poke me at @yozahoftheg on the site formerly known as twitter if there's anything that's broken beyond that. ouo)b
You may also tell me if there was some quicker fix and this was entirely pointless.
