Sorry for the wait! Done with my finals so now I have some time again.<br><br> ## Major Features<br> **Cave Drafts:** Ambient dust now dynamically calculates a pressure gradient allowing it to flow through cave systems (high pressure to low pressure basically). Dust should mostly go down long corridors, wrap around corners, and get sucked through U bends just like real atmospheric drafts instead of just bouncing off walls.<br><br> - `enableCaveDrafts` (Default: `true`): Enables air pressure and drafts inside caves.<br> - `caveDraftStrength` (Default: `0.85`): Multiplier for the speed of wind drafts inside caves. <br><br> In the case that you are worried about the performance of it, don't worry I have done a number of optimizations to it so it should have little to no performance impact except on older computers. The following optimizations were made:<br> **Environmental Collision Optimization:** Rewrote the environmental collision logic. The mod now uses fast fail checks that skip heavy collision calculations for empty air blocks.<br><br> **Wind Caching:** Added a new spatial caching system for environmental wind data. Particles flying through the same space share their pressure gradient calculations instead of doing the math individually. <br><br> ## Minor Features<br> **Minecarts:** Minecarts will now push the ambient dust ahead of them and disturb the dust.<br><br> **Cobwebs:** Ambient dust that drifts into a cobweb will now get caught and stick to it. <br><br> **Simplified Configuration:** Adjusted the internal math for multiple configs. Configs that used very small (eg 0.0001) numbers can now be written as 1 for 1x or 2 for 2x instead of 0.0001 and 0.0002.<br><br> ## Performance<br> This is a more general optimization.<br><br> **BFS Spawning:** Replaced the expensive per tick LOS raycasts with an optimized Breadth First Search flood fill. The mod now maps out guaranteed contiguous air spaces twice a second which should eliminate the wasted spawn calculations in solid walls.<br><br> ## Fixes<br> **Crash Fix (issue #5):** Fixed a ticking particle crash when dust attempts to interact with soul fire in the Nether. This occurred because I forgot to check if the fire block actually had directional properties (standard fire can attach to walls, but `minecraft:soul_fire` only burns flat on surfaces).
