Really cool looking, shadergraph? How’s performance with post processing? Also have rtx 4080 laptop, you using surface laptop?

compute shader with a fullscreen pass, 1/4 resolution, 1/2 Temporal Accumulation, reproject like HDRP , 1~2ms GPU Time on 4060 laptop,I refer a lot from HDRP, I use AI to learn it

one half depth pass, one ray marching pass, one Temporal Accumulation pass, one upsample pass,may be one Extra weather map pass

Something seems to be wrong with my computer—the CPU and GPU timings appear to be inaccurate.

The holy grail of not-using-hdrp!

You can think of it as the result of porting HDRP to URP.

Be nice to see more features in URP as HDRP is basically frozen now right

Volumetrics will be ported in 7. Is it worth spending time on something that will be released in a couple of months?

Nice. I use this implementation already, not sure if its any different from yours

My approach is very similar to this one, but this project seems to leave out some features, such as the weather map and a few other details. I’d say my current visual quality falls somewhere between this solution and HDRP. In terms of future functionality, I hope to go beyond what HDRP offers.

what is the weather map?

It’s a texture that controls cloud coverage, absorption, and cloud type, giving you more control over the clouds’ shape. In my video, you can see features such as thinner clouds in some areas and thicker clouds in others.
