Smoke Suppression is a client-side mod.
This mod prevents campfires from creating any particles when certain blocks are underneath them. It affects both standard and soul campfires.
This is to prevent client-side lag and general annoyance when using large numbers of campfires in farms.
The default list of blocks that suppress smoke is:
"suppressing_blocks_list": [
"minecraft:hopper",
"minecraft:rail",
"minecraft:activator_rail",
"minecraft:powered_rail",
"minecraft:detector_rail"
]
Blocks can be added and removed either using Mod Menu or by editing '.minecraft/config/smoke_suppression.json
Translating
If you'd like to translate Smoke Suppression (there are only a few lines of text), follow this link.
New translations will be added once approved without the mod needing an update thanks to CrowdinTranslate.
This mod is only for Fabric (works on Quilt, too!) and I won't be porting it to Forge. The license is MIT, however, so anyone else is free to port it.
I'd appreciate links back to this page if you port or otherwise modify this project, but links aren't required.
