My fingers come out broken even though they seem fine at the rigging stage

[Acid_Melon]

Hello. I have been working on my first avatar and I think it’s been coming out pretty alright but I have stumbled upon an issue when testing the avatar in-game. The right hand fingers look okay but the left ones are more messed up for some reason.

Here is a picture of the fingers when my actual finger is not touching the trigger

and here are pictures of how the fingers are rigged.

I am very new to this so I wanted to ask for some kind of help here. Thank you very much!

I know this is a couple years old, but I had a similar issue with my fingers twisting to the side like yours when using gestures. I had the same setup, with fingers that only had a single joint. In my case, exporting with leaf bones (from blender) and using the end part as the intermediate bone worked :>
