VR Expansion Plugin

I removed the pawn that was in the default template. And in my project, I began to repeat your lessons from the very beginning. I installed a new start player. Created VRCharacter … etc.
Everything as you show in your lesson.
First, I repeated your lessons in an empty template and everything worked out for me. The controller captures both the cube and the ball without any problems.
But when I repeat the same thing already in my project, it does not work.

I deleted all the blueprints previously created in the VR template. And he transferred the project from a successfully created lesson. And hallelujah!
But then I understand that I will constantly face new problems.

It is a pity that everything that I studied earlier in UE, does not work in VR.
I would really like to talk more with a person like you. And get invaluable experience in the work of VR. What is needed for ?
I have been working as a computer graphics artist for 30 years (3D mainly). I make various visual effects for television and advertising. Engaged in industrial design. And to be honest, I’m a little bored. Half a year ago, I first put on my VR helmet and I literally fell in love with thing. I devote all the time to business and I even got into trouble at work))

(I am not at all familiar with programming, but I consider myself a good artist))
