OpenFlares - Flare Guns!

The mod adds a flare gun item that is loaded with empty colored flare cartridges. Cartridges come in yellow, green, red, black, purple and blue, and the gun can be loaded, fired and reloaded with configurable controls. Crafting recipes cover the gun and the empty cartridges, along with colored cartridges. For each flare, the server runs the flight itself, applying the configured speed, gravity, drag, range cap, timeout, damage and smoke lifetime before sending the resulting smoke clouds to players.

A level-of-detail 3D renderer draws the smoke, letting a flare cloud stay visible beyond the vanilla chunk render distance once the server permits it. Clients choose among visual styles and smoke readability options, which help players tell colors apart when lighting or color perception varies. Adaptive occlusion budgets and optional missing-chunk loading keep the far-smoke rendering in check. OpenFlares needs Fabric API and Fabric Language Kotlin on Fabric, and Kotlin for Forge on NeoForge. A server running it needs every connecting player to have it too. The license is the GNU Affero General Public License v3.0 or later, and the mod is open source.
