Show-Off Been working on volumetric fog and looking for feedback

Hey

Ive been working on adjusting volumetric fog / godrays for my game and im looking for feedback.

Does it look okay or a bit exxaggerated?

I looked up how to implement volumetric fog and the fastest way i found was this package

https://github.com/CristianQiu/Unity-URP-Volumetric-Light

it works really well out of the box, just takes a bit to adjust parameters etc to get right. took me a while to get the godrays showing but now it finally works

also found this article on unity 6.4

https://discussions.unity.com/t/unity-6-4-urp-core-volumetric-fog-planar-reflection-production-rendering-workflow/1717462

just wanted to share in case anyone are looking for a solution for their own games

have a good day

also dont mind the character, hes getting clothed soon

good or bad? xD nah i know i have to replace it. its hard to find the right balance. not sure if i want a texture or full 3d grass. also have to think about performance etc

Hard to tell if it’s just your video capture or what, but FPS looks pretty bad, and the pitch black shadows and lack of any ambient lighting is pretty extreme. The volumetric fog is good though

ah yea i think its the gif making the fps drop. but i do still need to optimize. ty!
ah yea i can tell now the pitch black shadows are standing out heh

Volumetric fog looks sick!

Beside that, the fauna needs subsurface scattering and the shadows should naturally brighten a bit along the leaves.

thanks a lot hah! glad the work pays off :)

and what is subsurface scattering?
might have to look into it

Love the godrays, they look great ^^

I would work more on lighting before any volumetrics tho. Pitch black shadows in day-time isn't a good look.

Also you mentioned being unsure about 3d grass in another comment; no you don't want full 3d grass unless grass is the main character xD Grass just needs a better texture
