How to set up the new Water System

I've been trying to find out how to set up the new water system that came initially with 2022.2.0a9. It wasn't that straightforward, so I thought I'd make a post for others.

* Project Settings > Quality > HDRP > Rendering > Water


* Project Settings > Graphics > HDRP Global Settings > Water Rendering


* Hierarchy > Water Surface > Ocean



In case everything is white like it was for me, adjust the Exposure in your Sky and Fog Volume.

Looks like this then:

 

Is the water system also compatible with Unitys path-tracer?

 

How do you add this into 2022.1.7f1 manually?
Is there a specific preview package we can add to start working with it before 2022.2.1 is released?

 

Hello,
I've followed the above and still have no water rendering.
You mention Project Settings > Quality > HDRP > Rendering > Water
There is no option for CPU

all other options regarding water are ticked.

Sys spec : ryzen 5 3600 CPU
AMD RX480 8GB GPU
using windows 10 home edtion.

Any help would be appreciated thanks.

 

I am using Unity 2022.2 beta, and doesnt work, i have all water options activated, i create an Water surface object and no water is rendered. I dont have some of the options shown, also can't find anywhere the Volume override mentioned in last post. I reinstalled hdrp as mentioned in last post and that just made the project not work at all, there is not global settings for hdrp and get lot of errors.

 

I removed the project, created a new hdrp project and just activated water system in hdrp global and in quality hdrp, then created a Water surface object of ocean type, pressed play and no water is rendered

 

did you added Water Rendering to your global volume ?

 

Yes, found the problem some days ago, the problem is that besides that you need to add water as one more volumetric effect ins hdrp settings

 

i followed all your steps and i also didnt get a water surface only the icon.

then i added a global volume to the project, and add the water component checked all the boxes.
and yes there is now visual water

 

anyone knows how too get buoyance on like boats? like they move with the waves?
i know there is 2d buoyance. but i couldnt anything like this for the new water system.

which looks really good. with the caustics and underwater settings.

 

Depending on which version you are, the WaterSurface script, there's an API to query the projected position of the current water surface at a specific position (basically to make an object stick to the surface).
After that, it's up to users to create the buoyancy system depending on their needs

Im on 2022.0b4 beta.

too bad it isnt a physic droppdown option.
like you have with the 2d Buoyancy

 

@chap-unity Is there some integration or instruction about how to use rivers with the unity splines?

 

I hope the unity splines package gets integrated into water and terrain systems like unreal. This is important, a lot of users would love that.

 

Is it expected that water does not work when MSAA is enabled (forward rendering)? I have spent too much time figuring out why water is not rendering and MSAA was the culprit. Is there any way to get water + MSAA? (Unity 2022.2.0b8)

 

Thanks for the answer. I am curious what technical limitation causes this? How MSAA interfere with water rendering/simulation?

 

Is anybody else experiencing this issue where caustics are rendered as triangles?

This is in a fresh outdoors template in 2022.2.0f1 with nothing but water and a plane underneath it added, HDRP and water surface are on default settings otherwise.

 

Talked to a Unity dev on Discord about this issue, as expected it's another easily reproducible issue on AMD GPUs.

Kind of sad that I'm the first to notice something this obvious since the water system has been in development for some time. This is a pretty tame case since this isn't a crucial feature in an LTS release for once, but still another clear indicator that Unity simply isn't developed or tested on desktop AMD cards.

At this point not buying into Nvidia has become an actual liability, and I'm feeling more and more like I no longer have a choice unless I'm willing to put up with tons of downtime writing bug reports, looking for workarounds, and potentially missing a deadline over undiscovered AMD-specific issues that may or may not be fixed in time.

 

Wow that is really bad

 

It works great in Game mode and Editor, but the water does not show in build.

 

What does it mean when "Water" is not under these settings. I've been trying to figure this out for weeks.

 

How did you make reflections work , mine only reflects sky maybe
