Just the other day, I saw a mod where someone had replaced the crappy dragonbone arrow model with the steel arrow model.
I liked the idea, but I thought the dragonbone arrow should be much different. After much trial and error getting the model to work in Skyrim, I present my interpretation.
Version 2 uses the fixed arrow.nif from the UDGP.
Dawnguard is required. I repeat, DAWNGUARD IS REQUIRED! These are meshes only. No textures, no esp.
