High Performance Raycast Rain

What is it?

A simple rain script i made, its client sided and uses multithreading. Ive made the script as optimized as I could. Each rain drop is its own raycast and the script has rain sounds for outside and inside.

How Good Is The Performance?

The performance is really good with almost no frame drops.

Would you mind turning this into a module? It would be lovely to Enable it and Disable it anytime i want in-game. I really do need a new rain system for my weather system… With this being said… If you do turn it into a module in the future could you also add a :SetIntensity(intensity: number) function to it? The higher the number would be, the more droplets there would be and the other way around.

A great feature to add would be a :SetDirection() function that allows the rain to fall in a specified direction. Right now, it only supports vertical downward motion. I’m not sure if that’s achievable with ParticleEmitters, but it’s definitely possible with Beams. Adjusting the Rotation property of the “Trail” ParticleEmitter might also work, who knows!

Hi, did you play with it to see if the direction of the rain could be changed? like not straight down, but at an angle?

Thanks

Not really. But it is technically possible using the Rotation property of the particleemitter.

I have turned it into a module though and implemented some useful features…

This is entirely unusable in a real project due to it using up over 300+ draw calls on just the rain in a baseplate

This can cause many performance issues on large maps, and I hope you can address this problem in future updates
