Quick question. I want to spawn some footsteps, paint stains and other things on the ground. Player will have a task to clean the floor from them.
Is it better to have them as decals or separate meshes and why?

Hey @codeedward1!

That would really depend on your aesthetic and what you are going for, but because these are all flat, it may be best just to spawn an actor with a decal that will behave in the way you want it. This way you can control collision, special behaviors, etc.

For example, you spawn an actor on a wall that is a decal, as you “clean it” you use the actor’s blueprint to make the decal smaller, etc.

Good luck developing!

@MikelKram First create DecalActor, then use SpawnActorFromClass node.
