Rain effect

guys what about rain effect like light…etc
really its not available in unreal 4.0.1 ???

What do you mean with “rain effect like light”? And also you’re using UE4 version 4.0.1?

Why not use a particle system?

You can make a rain effect in any version of the engine.
It’s not supposed to be available out of the box, this is a game engine, not a mod tool for some game.
You’re supposed to use the tools provided by the engine to create your own content.
