Hi,
I know this thread is a little old but when I saw your tutorial and the results it gave along with the free stuff, well I had to try! (sick tutorial by the way man your one really cool guy).
However,
I have a problem 
I have followed your first tutorial for the ledge grab system, I downloaded the new animations on your website rather than the old placeholder animations, I’ve imported them into UE4 and all looks good!
Here is a video though showing you my problem, I go through the graph in the video (video quality is a little bad, hopefully you can see the graph though) and right at the end of the video I show what is happening with my character. I followed the tutorial all the way through and haven’t gone away from the methods you show in the tutorial, the only difference between my project and the one in the tutorial is that I have moved the camera and attached it to the characters head socket, all values for the tracers are as they are in your video (I started with the 3rd person BP template).
[video]Dropbox - Error
If you need access to the project I can upload to Dropbox so you can see what I have done, I’ve been scratching my head over it, I don’t know whether the values for the tracers in my project need to be different, or whether there is something wrong with the animations and their states. I would really love your help debugging this though as its killing me
Keep up the great work though bro, would love to see more tutorials and if you haven’t already got a hard drive then drop me a PM, I will gladly buy you one 
Cheers,
Dave.
