Thank you for the information, however I think I will need your tool, I can build the actual galleries with UE4 and use your code snippets for the control of the player/user and to give interactivity to objects and portraits in the gallery. The link you sent me https://theziumsociety.itch.io/is of no use to me as I can't build my own galleries with this software.
The pictures is a gallery I created using UE4 however I am at a loss when it comes to player control and manipulation of objects, I really don't have the time or interest in creating such controls.
Thanks for your time, once I have have the experience in using such codes etc. I will probably purchase your code snippets as it looks to more than cover what I need.
