Distance Fog (using Forward renderer) - how to make it cheap?

Hello devs!

My team is working on a VR game with quite long view distances and we've been trying out different solutions:

Exponential height fog actor - too expensive
Custom post-processing material - too expensive as it requires Mobile HDR to be enabled
Planes with cloud textures using alpha-masking with Temporal Dithering - too expensive

Anyone got other nice practises on how to do a performant distance fog? Or is it always an expensive trade-off?

Thankful for all input!

Depends on what you can get away with game play wise. If you don't need to change it in real time, you can pre-bake it into vertex color.

That's actually a good idea, Pre-baking it should work. Thanks for the input!
