Light Dust

Major Features

Weather Wind system update: It has been rewritten to simulate real fluid dynamics. Wind now utilizes prevailing weather directions mixed with localized gusts, causing dust to swirl, sweep, and flow. Wind exposure is now calculated using a sky light gradient, allowing drafts to naturally bleed under trees and overhangs as well as tunnels and holes.

• enableAdvancedWindMath: Makes the wind look realistic and natural. Instead of blowing in a straight line, the wind will swirl, sweep, and create gusts of dust. [Performance Impact: MODERATE-HIGH] Turn this off if your game lags when surrounded by blowing dust.
  
  

Dust Deflection: When the wind blows dust into a solid wall, the particles will realistically transfer their momentum to bounce off the obstacle or slide down tunnels, this should create natural wind drafts in narrow corridors.

• enableWindDeflection: Allows wind to blow dust down tunnels and bounce off obstacles instead of getting stuck and disappearing. [Performance Impact: LOW] Safe to leave on for most computers. Only turn off if you get lag specifically inside tight caves or narrow hallways.
  
  

Dynamic Lights Compat: Ambient dust now reacts to handheld light sources. Holding a torch, lantern, or other luminous item will dynamically spawn an area of dust. Fully compatible with items equipped in Curios and Accessories slots. (Note: You still need to actually install a dynamic lights mod. This only spawns the dust).

• enableHandheldLights: Master toggle to turn dynamic handheld dust spawning on or off.
  
  
• handheldLightItems: A customizable list where you can define exactly which items act as handheld lights, including their dust spawn radius and the color tint of the dust.
  
  How to configure: Use the format namespace:item_id=radius,#HEXCOLOR for specific items, or #namespace:tag_id=radius,#HEXCOLOR for entire item tags.
  
  
• Example 1 (Item): minecraft:torch=14,#FFCC00
  
  
• Example 2 (Tag): #minecraft:candles=10,#FFD700
  
  

Performance

Entity Disturbance Optimization: Optimized the experimental entity math. The system is now hard capped to only track the 6 closest moving entities. This should make it so mob farms and the like should no longer lag a crap ton.

LOD & Movement Prediction: Overhauled the spawning logic when the player is moving quickly. The system now dynamically shifts the spawn area into a forward facing hemisphere, predicting your path and spawning dust into your line of sight. This was done for dynamic lights as otherwise it would eat up your FPS (no seriously it would go from 120 to 70 when outside and affected by wind, its not nearly as bad now.)

Occlusion Culling Update: The ambient dust raytracing system has been optimized with a strict hardware budget cap to prevent CPU bottlenecks. The system also now skips LOS checks if both the player and the target block are outdoors.
