Hey, so I've had this issue before and never actually found out how to fix it, so the model when on a surface appears dark, as if he was im the ground since when you jump, he becomes the colour that he should be, I've tried to make the reference legs higher up in-case those were the problems, doing the same to physics file and nothing changed, even if it shows the legs not even touching the ground.
Here's some images/gifs:

As mentioned before, model looks good when in the air, on the ground he appears black/dark, which is what I'm trying to avoid, I can use UnlitGeneric but I'd like it VertexLit so it can actually look good in shadows, anyone know a way to fix this? Thank you!
