Hello fellow devs,
I’m trying to create a similar surveying system I really loved in the game “Star Wars Galaxies” (SWG).
You would have a surveying tool in your inventory, set the radius of search and just use it…
Here is a video on how surveying works: Youtube Video
Now I have no problems creating the survey tool and using it. I created a blueprint with a Static Mesh, set a collision box to block my ResourceTrace channel with a sphere trace. It all works fine, but this would mean to actually spawn static Meshes in the world. This is the part i actually don’t want.
in SWG, there was no physical representation of resources in the world, it was just “data”. This is the part I can’t recreate and need help with.
I already thought about just deleting the static mesh, which of course works, but it’s not how it’s supposed to work. I’d like a map with resources, if possible dynamic, so resource type and concentration can change over time.
I have absolutely no idea where to start 
Thanks for your help.
