Hello Molarin,
If the idea is to simply view different models, it may make more sense just to change the model.
In a Blueprint create a Static Mesh Component, then use the “Set Static Mesh” node to swap models.
VR Implementation should be as easy as selecting “VR Preview” play mode.
If you know how UVs are set up on a cube, you should be able to author a texture for it (then create a material with that texture and assign it to the cube)
Hope that can get you started!
