Hi Folkz!
Is there any good Tutorial out there on how to create nice looking rain, clouds and maybe weather effects like Thunder?
On YouTube i didn´t found for what im looking for.
Greetings!
There is another thread about this topic: SEE HERE!
This is what you should try:
[QUOTE=DotCam;113277]
Download the “Effects Cave” demo from the UE4 launcher’s Marketplace, it has a working snow particle effect, thick clouds/fog (fogsheets & fog/cloud particle effects), and using one of the dripping waterfalls as a base, you can modify the particle system so that it looks more like rain (increasing the area of effect, etc).
Plus all of the content in there can be used in your project (this is true for all of the items currently on Marketplace), this will give you a jump start to making your own versions, and learning how they were created. 
Hope that helps!
