Cast light on volumetric clouds

[Arkiras]

So everything else has to be “faked” through the emissive of the cloud material?

I would not describe it as fake but yes you need to do it in the material.

@LordStuff

But how’d you do something like airplane searchlights? Anything like far range spotlights basically… just curious

Same way you’d do lightning. Define the volume of the light cone and use the clouds emissive output. The only thing you can’t really do easily is shadow casting.

For what it’s worth, someone has already put together a system for automating this on the UE marketplace: Clouds Lighting System in Code Plugins - UE Marketplace
