How to avoid still drawing objects completely hidden by VFX particles?

Hi,

I created some fog / smoke particles when my player is in heavy rain. when it's the heaviest, it completely blocks sight for a very short distance.

However, I can still see the outlines of 3D meshes. See image:


How can I avoid that?

Thanks!

 

Unlike all video games, my game is about realistic weather simulation. So a rain shaft has to look like this:


I unfortunately can't do such an effet with a regular fog effect.

Anyway I found a workaround : Considerably reduce draw distance of my camera when inside the heavy rain.
