Hello,
I will develop a floating object selection system that will fly and accumulate the objects when clicked on top of them as you have described in the attached image + description.
I've been developing games and technical prototypes using Unreal Engine for about 5 years and I think that I meet the requirements to complete this task.
Everything will be done using blueprints for clarity and will be done using Unreal Engine 4.26 as you have requested.
Feel free to contact me via 'Chat' to provide more details/ discuss the project.
