Version 8.4
For UE 5.1, 5.2, 5.3, and 5.4
Added an option to Shared Particle Settings on UDW to apply a custom weather particle camera transform. If true, vector variables for a custom camera location and forward vector will be used instead of player camera 0. Can be used to place the weather particle systems spawn area in any location if needed.
Improvements to DLWE snow trail rendering. Trail edges now have a soft piling normal effect in a radius around compressions. This is specific to Shader Model 6.
Added an option to UDS Occlusion Settings to have player occlusion use GPU distance field traces, instead of the simple collision traces on the CPU.
Added an element to the rain particles for small impact ripples from raindrops on surfaces. Toggled by a setting in Rain Particles, and enabled by default.
Changed UDW Thermometer to use basic letters for its scale display instead of the special ℉ and ℃ characters, for compatibility with fonts that lack those characters
Added a function to UDW, Generate Weather State at Location, which can be called to create what would be the local weather state if the player was in a custom input location. Can be used to query the specific weather at any location in a level.
Added a setting, Splash Minimum Z Normal, to adjust the angles of collision which rain splash particles can spawn against. The new default allows splashes and splash droplets to happen against more vertical surfaces.
Added support for rain drop decals and splash droplets to the distance field collision version of the rain
Made it so sampling temperature from UDW at a custom location will take local sources of weather at that specific location into account in addition to interior temperature and temperature volumes.
Made it so distant lightning bolts can appear in a path tracer render, when Adjust for Path Tracer is enabled.

Version 8.4A Hotfix
For UE 5.1, 5.2, 5.3, and 5.4
Fixed a bug which could break distance field collision for weather particles past a distance from the world origin
Fixed a visual bug with tiling stars on the lower sky hemisphere in Space mode
Fixed an issue with cvars UDS applies not being reapplied when unloaded and reloaded within a data layer in a packaged build
