Hello Oleg,
This is a actor you can drop in the scene just like meshes or lights. It is available from the Visual Effects menu:

Awesome! I wonder when they will be available with Path Tracer?

[SebHillaire (Sebastien Hillaire)]

Thanks!
No ETA as of today but I will mention it to make sure it is on the road map.

That’s the kind of tutorial I enjoy. Short, precise and some cvar magic at the end @SebHillaire is local fog volumes only available when there’s a exponential height fog? And does local fog volumes work with the forward renderer?

[SebHillaire (Sebastien Hillaire)]

Hello @tomaaron872 ,

Thanks!

It should work with deferred and forward renderer, opaque and translucent (need to enable a cvar for translucent). You can use LFV without paying the cost of HeightFog component if you want to. However you do need the height fog component in case you want VolumetricFog (a dependency we should remove in the future).
