Problems with raycast accuracy

Hi everyone!
I have problems with a raycast accuracy.
It’s must instantiate blood prefub when it’s hits a collider, but it’s missing, and it’s recognizes a collider in air, where is no any colliders.
As you can see on the picture, raycast hit’s on the left of the collider, and he think that he hit hand, but in fact it missed:

Anybody knows ,what’s happening and how to resolve it?
Thank you!

Guys , resolved that stuff by changing an Update Mod in animator from “normal” to “animate physics”.

That’s solve my issue!
