This function works well - there is however a small issue when the rain function is configured to produce snow particles instead of rain drops. At scale >0.02 the default texture looks like a rectangular postage stamp with has dark lines on it which detracts from immersion.

Steps To Reproduce
Run BIS_Fnc_Rain as detailed on https://community.bistudio.com/wiki/BIS_fnc_setRain via the debug console and configure to produce snowdrops. Watch the default raindrop texture suitability at scale ~ >0.02. The default raindrop texture needs to be replaced with a more realistic snow particle texture - that looks less like a postage stamp (see images below) than a snowflake. If you substitute the aforementioned texture for "a3\data_f\snowflake4_ca.paa" - this looks better but is still not ideal when the particle is close to the camera.

Ok I've amended this ticket. My apologies for wasting your time - it was my mistake - I still had a mod loaded that caused the water splash particle/decal issue.
This morning I tested the function on 40+ maps with different texture scaling and settings and the function works perfectly and no snow impact water effect.
As far as the snow texture is concerned - I've attached two images showing the the default "a3\data_f\rainnormal_ca.paa" and the "a3\data_f\snowflake4_ca.paa" textures for comparison. Not surprisingly snowflake4_ca.paa texture looks best but not ideal when the texture is close to the camera. This is not critical but would be a nice to have improvement.

"a3\data_f\snowflake4_ca.paa" it means it has 4 flakes in it, you are using it as 1 flake

Thanks KK - excuse my ignorance in the context of BIS_fnc_setRain how do I reference the (presumably) first frame in the sequence of snowflake4_ca.paa? Like this?
// texDropCount isn't documented from what I can see.
After subsequent testing the answer is yes! Excellent thanks.

I've updated documentation yesterday
rainDropTexture: a3\data_f\snowflake4_ca.paa - texDropCount: 4
rainDropTexture: a3\data_f\snowflake8_ca.paa - texDropCount: 8
rainDropTexture: a3\data_f\snowflake16_ca.paa - texDropCount: 16
