Hi,

I’d like to recreate something like that

[American Gods - Opening Title Sequence | Prime Video - YouTube](https://www.youtube.com/watch?v=eBkoG-8E-2w) -\> first few seconds - especially the tree at the beginning.

Is it possible the create some kind of smoke that is illuminated by lights?

I’m not sure to understand what needs to be done…

Maybe you can use the glow layer ([Making Meshes Glow | Babylon.js Documentation](https://doc.babylonjs.com/divingDeeper/mesh/glowLayer))?

Would be easier to help if you setup a basic playground as a starting point.

Well I can’t set up a Playground because I don’t know how to achieve it 😃  
Basically I’m trying to illuminate Fog in different colors if thats helping to make it more clear?

In that case, you can simply change the fog color dynamically and use brighter/darker colors:
