Rain Particles Doubling with Anti-Aliasing

Development Rendering

Hi,

I’m using Unreal Engine 5.3.2 and when I render rain particles using Anti-Aliasing, setting the Temporal Sample Count any higher than 1 renders multiple instances of the same particle.

I’m using Ultra Dynamic Sky and Weather for the Rain Particle System.

I’ve tried using other Anti-Aliasing methods like TSR and MSAA but I get the same result when I increase the Temporal Samples.

Can anyone help me with what’s going on with this?

Thanks in advance.

Hi OP did you ever find a solution to this? I’m experiencing the same thing more or less with my rain scene. It’s a static shot of the ground with rain hitting it, within a couple of frames it starts to look like a pool.
