When an asset is demonstrated in a video on the marketplace then it is assumed all the features in it work in the example. Then there was several videos that, a minute into the video, point you to a new version. The guide on the wiki explains all in great detail, but at the top of the page refers to a 4.9 video. That video explains how to set it all up easier than in previous versions. However it leaves out that you still have to add in a lot of things manually. So after the initial confusion on what video guide to use I had to manually fish out all the functions and carefully recreate them in my own character. And I assumed the outline was part of that, somewhere buried in the JC functions, almost none of which have tooltips that explain what they do. This created quite a bit of confusion and was not just a 15 minute install like the shop description advertised. All of this could have been avoided if there was a written or video guide that explictly explains all of the parts that have to be manually ported. Someone who is actually new to UE4 would have had far more difficulty porting the code over himself. And a warning that it is indeed not a quick 15 minute install would have managed expectations better.
The functionality of the code is great, but the documentation and commenting of the functions leaves some room for improvement.
