Hey Hardcaw
I liked your idea and tried it out but it sort of worked but was difficult to manage especially when you have a pile of chests on the island. It also sometimes failed to trigger, and at other times it multiple triggered on entering the volume. The last one I think I fixed but it still wasn’t really suitable.
I went even deeper down the Verse rabbit hole and finally came up with something that works. See pic below where my chest is one on the right. There is an issue with visual cues for the sound which I’m pretty sure can’t be done in UEFN but happy with the rest as it can spawn anything you want. I also have a lot of other textures and sounds from Fortnite, so will look to make other different style chest to spawn other things.
Hats off to a Reddit post from Honeydewmelo who showed how to use Verse for multiple chests.
Here’s how to make them! (Custom Chests 2.0 Tutorial) : r/FortniteCreative (reddit.com)
It’s a shame that people have to go to such lengths for what should be a basic Fortnite gameplay asset but presumably the devs have their hands full with other stuff and hopefully modifiable chest will make it’s way into UEFN in the future.
Cheers
