Hey, I love this mod and what you are trying to achieve with it. The standard anims are certainly kind of basic and doesn't really allow for a deeper experience.
There is although a few things I want to point out to you. I have used this mod quite a lot and this is what I noticed:
* The "walking" anim moves in slow motion in MP, but not to yourself, only to others (You probably know about this one, pretty obvious)
* That thing about the game checking for structures/walls to enter back-to-wall mode or climbing, it's completely unnecessary and it doesn't work (You seem to be on your way fixinig this too)
* Using space+E/Q to do back-to-wall makes it easy for you to accidentally start sprinting, I would prefer the alternative to use a separate button for this as in previous versions. It works though, so it's not a huge issue.
* Leaning against a wall from the right side is a pain if you're in expert/first person. Your guy makes kind of a pirouette to get in and out of the position. I can see why it is this way, but it's very confusing for your guy to start doing dancing steps when in first person. If the right-side were more like left-side anim it would be awesome.
I know this latest version is just a RC, but if you fix the "slow motion" bug and remove structure check this mod would be damn near perfect. Keep up the good work and thanks for an awesome mod!
