Light Dust Mod (1.21.1, 1.20.1) – Watch Glowing Dust Motes Drift

Light Dust Mod brings floating dust particles that react to illumination, weather, and motion across your world. Every light source creates gentle motes that drift realistically through rooms, caves, and open landscapes. The particles respond directly to the environment, blowing faster during storms and rising above hot blocks. You can fine-tune every visual detail and performance setting right from the in-game menus.

Features:

• Light sources generate floating dust particles that match the surrounding illumination.
• Particles react to physical forces like wind, player movement, swinging tools, and nearby explosions.
• Breaking blocks creates debris bursts and pulls nearby ambient dust toward the broken block.
• Heavy landings kick up a ring of ground dust and push nearby particles outward.
• Updrafts form above heat blocks to lift floating particles into the air.
• Particles adopt colors and tints based on the biome and surrounding blocks.
• Wall occlusion checks stop dust from appearing inside solid blocks or behind walls.
• Built-in options let you pick between fast performance calculations or detailed spreading patterns.
