GTS - How to use Rain settings?

[h2hjastermereel]

If I select Rain settings for GTS it applies them instantly on the terrain, but obviously I would only want this to show up if it is actually raining. How do I configure that?

Hi @h2hjastermereel, it depends a bit what "actually raining" means, do you use a weather system in your project? The rain weather effect in the HDRP Time Of Day system should already be synced up with the rain settings in GTS.
Other weather system would need to be synced with the global rain power shader setting that controls the strength of the rain effect. The power is encoded on the y axis in a global vector called "_PW_RainDataA".

Any plans to back port the weather system back to the SRP?

We plan to support URP as well, but no plans for built-in rendering - built in is supposed to be replaced by URP at some point in the future so we try to not invest too heavily into it anymore.
