About this Mod

Banner artwork

Disclaimer All in-game textures/sounds are from 1.21.5 made by Mojang. I did not make them.

This mod simply brings the firefly bush from 1.21.5 to older versions. It works as similarly to the original as possible, emitting firefly particles around itself at night or in a dark environment and playing ambient sounds at night. It can be found in swamp biomes or near any body of water.

This mod comes with a client-side config file. The config allows for tweaking the behaviour and visual aspects of the fireflies.

FAQ

Can I use this in my modpack? Yes, go for it! Just make sure to use the appropriate source for your modpack (Modrinth/CurseForge).
Will this be ported to x.x.x version? Feel free to open up a version port request on my issue tracker and I will see what I can do.
