I have a fully rigged and animated character with shape keys. I created it in 2.79, exported it using ASCII with the settings below and could use it in Unity without any problems.
However, after opening it in 2.8 and trying to export it, I realized that ASCII is no longer an option. I looked up tutorials on the binary export settings, but whatever I do the animations look weird in Unity. To be precise, the arm is deformed at the elbow (I have an IK setup and use baked animations).
I also find animations attached to the body when opening the character in Unity. These do not actually work (the character doesn't move) but I have no idea why are they there to begin with.
What export settings should I use in 2.8 to avoid these deformations? Or do I need to modify something on my model to be able to successfully export it from 2.8?
