Being a huge Cinema fan, one of my most characteristic things to do is spray my images in the theater room with my mates. They’d often be humorous quotes, select images from our favorite videos, etc.
Sprays are a huge part of my Cinema experience. We have a ritualistic need to spray the theater each time we begin our session. I know it may seem like a weird and insignificant feature, but it helps personalize the environment even further!
To bring another, modern example of this, look at Splatoon. There’s a feature where you can ‘tag’ walls in the world of Splatoon with your own design.
As far as I know, spraying is a wholly Source related feature. I’m not sure how best you may all be able to translate this into Unreal, though I would extremely appreciate any sort of attempt!
Thanks for the consideration!
