Looking for rain, fog and snow effects.

[k4far]

I would like to lower opacity to improve the performance outside of Kamino and overall.
In the MB2Effects folder there is smoke but, I could not find the rest of gfx.

Lowering opacity won't help. Opacity is taxing to the renderer no matter what the opacity level is. You will want to reduce particle counts.

Rain, fog and snow are generally handled by JKA engine. Any map specific effects are generally in the map's PK3 file.
