Package repo containing the water system created for the URP Boat Attack demo project.

Boat Attack Water

This repo contains the Unity package for the water system that is used in the Universal Render Pipeline demo 'Boat Attack'. The package is under constant development and is not supported in any official capacity.

boat-attack-water's Issues

Water Shader turns Purple in 2022.2.11

Looks like the water shader isn't supported anymore in the 2022.2.11f version.

Does not work with stace orthographic camera

I have a base camera with a stack of 1 orthographic camera. The water does not work with your version of the water.
I have been using a relatively older version (extracted from the official boat attack demo) that works fine with my setup.

UNITY_REVERSED_Z not defined on 2021+

Hello. I have been trying to build using WebGL. It all works very well on i.e. Unity 2020.3.25f1, unfortunately when trying to do this on i.e. Unity 2021.2.10f1, I get an error in the Water.shader file saying: UNITY_REVERSED_Z is not defined. Unfortunately, I don't have any idea bout shaders. Any idea how to fix this? Thanks ~

Make reflection enable / disable based on camera

I have 3 cameras in a scene: Main, Satellite, Froward Gun. I would like reflective water, but only on the Main camera. Is it possible to have a way to enable / disable reflective water so its only reflective on selected cameras? So on a per-camera basis?

Water not rendering on iOS

I have the depth and opaque texture enabled, but the water doesn't show up on iOS 15 (iPhone 6s). Using Unity 2020.3 LTS. Works on all other platforms. Original water from Boat Attack demo also works.

Expected result:

What I get:

Package is not compatible with 2020.3

The package uses C# language features which are not supported in 2020.3:

boat-attack-water/Runtime/DepthGenerator.cs

Line 89 in f61861f

if (UVPos.x is > 1 or < 0 || UVPos.y is > 1 or < 0)

Either this code should be changed, or the minimum version in package.json should be raised to 2021.x.

Reflections not working properly in VR

Unity 2021.2.14 - Oculus XR plugin 1.11.2

Editor looks good

VR Multi-pass rendering - reflections are half the width they should be.

VR Single-pass instanced - much more broken...

Changing Render distance on shader?

Awesome asset!
I just have 1 little issue.
Above you can clearly see, under the camera (the shader I presume) renders a circle of high quality waves. But as you can see from this distance its way too small.
I tried adjusting the LOD parameters on the water meshes, but it doesnt work unfortuately, I also tried to scale the water model meshes (in import settings) but again it didnt work unfortunately, so thats why im thinking this has to be a shader.

How do I increase the size of that render?

Thank you!

The UNKNOWN_OBJECT_TYPE WaterDepth.DepthValues

When I attach BuoyantObject:

Water not showing in Windows and Android Build

• I am using Unity 2022.3
• Building windows or android game water is not showing.
• Please help

UNKNOWN_OBJECT_TYPE WaterDepth.DepthValues has not been assigned or constructed

Getting this error, Ive tried different things but to no avail, this is the first time im working on a Job/Burst system though.

InvalidOperationException: The UNKNOWN_OBJECT_TYPE WaterDepth.DepthValues has not been assigned or constructed. All containers must be valid when scheduling a job.

WaterSystem.Ocean.LateUpdate () (at Assets/boat-attack-water/Runtime/Ocean.cs:218)

As this project wasnt a .unitypackage, I just dropped it into my Assets folder as you can see, maybe thats why its breaking?
All WaterSystemSettings, WaterResources, etc (Scriptable Objects) are all set and filled in as they should be. No other errors. I already tried changing the settings on those SOs but that doesnt seem to be related and working fine.

Does the scene in the screenshot exist?

Weird water clip-off (Linux, Vulkan)

I'm running Unity 2022.1.5f1 with URP 13.1.8 and the GitHub version of Boat Attack Water. I'm getting this weird cutoff no matter what settings I use both for URP and Water. I'm using Vulkan with an Nvidia GPU on Fedora 36.
