Hi!
Quivers usually are on the back or on the right hip, so they won't be in the way of the sword.

Actually historically they weren't used on the back much. You can place them with the configs tho. Also for the hip I was sure I placed them in the appropriate position depending on the player main hand as people would use their other hand to draw arroes

I saw the config, thigh is the right place to render, because it's on the belt and hangs down to the thigh, not the hip – sorry –, but I don't know how to change the rendered place to the right. I tried the Wiki and the config, but nothing yet.

so from what i can see they are on the left as they should be placed in the opposite side as to where you hold the bow to not get in the way of the bow. That's the historically accurate location
