Disclaimer: Sorry if my writing is not clear, I am a bit hungover because of the holidays, I will come back to this and make it clearer.
Hello there! For anyone that is using this and doesn’t know where to start or anything I recommend the following.
Get this book https://www.amazon.ca/Unreal-Engine-VR-Cookbook-Developing/dp/0134649176
Yes, the book may be a bit old, but I find its contents still hold with the current version of the engine. (I am currently running 4.24).
The great thing about it is that it walks you through creating a VR project from scratch and it uses a similar approach to the TraceInteraction Examples in the project which by the way can also be updated for 4.24 without many things breaking.
I suggest you don’t try building the project as is, instead read the book and use the project as a reference for things the book does not explain or stuff you don’t understand. Create your own project and see if you can move stuff from the 's project into yours, that way you will have more control and more understanding of how everything works.
I like to think of the book as a companion guide to the VR Content Examples project that is on . It was really helpful to me as I got an understanding on how to do things without much hassle.
As a final note, if you created a VR Template using Epics launcher, do not use any of their built in stuff, you will get confused and lost in weird details. Make a VR Ready project, but start from scratch.
