[WIP] VR Essential Kit

Hi ,
can you help me? I have this Essential Kit, its realy good but I have one problem.
First I tested make manualy all in new clean project but still I had problem with collision and grab system.
Now I have imported all into my project. Function is good but I have my camera view still down or under floor. I can not solve this problem.
And if I look on some blueprints then I see some old definiton.
I use engine 4.21.2 - can you change it for this version or send me some fixed files or something?
THX very much
