SSE creating/editing custom projectile model?

[Wolfar15]

So I'm trying to create a mod that would be an addon for Hunterborn SE that would add Bone Bolts crafted through the scrimshaw system similar to the bone arrows already available through that system. The single hiccup I am having is in the Projectile section for each bolt. I need custom projectile data or else I'll have to rely on Steel or dwarven, then when the bolt is shot it will show in the world as steel or dwarven bolts in both name and appearance until picked up again. I've never done anything like this before and I don't know where to start. I've thought about using assets from other mods where the authors have given their permissions but I don't know how to get those assets into my mod or even get them to show up in the drop-down box for Projectiles in the CK.

In creation kit, they are under SpecialEffect/Projectile. You can duplicate a vanilla one there to create your own. Then to get a new model, extract a projectile nif from the Skyrim - Meshes BSA. Open it in nifskope, open the nif model of the new projectile you want to use. Right click on the BSTriShape from the new model and select Copy Branch. Then in the vanilla model, on the very top BSFadeNode, right click and select paste branch. Then you can delete the triShape of the vanilla model you don't want. Save as a new nif, and put it in a meshes folder so you can use it in your new projectile in the creation kit. Hope that helps.
