The Community Ocean Shader (Open Source) Unity 5

Hello everybody, I love the work you've done with this asset and I would like to use the shader in my project.
I already have my buoyancy physic and my ocean wave script working pretty well.
So, I was looking for a shader for him (I don't know anything about shaders).

The problem is that my ocean mesh is moving and rotating with my camera ( to optimise triangles ) and because of that the texture also moves and rotate with the camera what is very weird.

Is there an easy way to avoid this ?
I try to change some parameters in the shader but with no results.

Thanks.

 

Hello.

I think you should apply worldUV map on the shader to avoid this.

Search for //World UV's in the shader and replace the appropriate variables.

 

Thanks elias_t for your help.
I found 2 commented sections with //Word UV's title in the shader under LOD5 and 8.

In LOD8 these lines are commented:

Code (CSharp):

1. //World UV's
2. o.worldPos = mul(_Object2World, v.vertex).xyz;
3. o.bumpuv.xyzw = o.worldPos.xzxz  * _WaveTiling*0.005  + frac(_Time.xxxx * _WaveDirection);
4. float3 worldPos = mul(unity_ObjectToWorld, v.vertex).xyz;
5. o.buv = float4(worldPos.x + _CosTime.x * 0.2, worldPos.z + _SinTime.x *0.3 ,worldPos.x + _CosTime.y * 0.04, worldPos.z + o.bumpTexCoord.w )*0.05;

But it Only Work when I uncomment the 2 last ones:

Code (CSharp):

1. float3 worldPos = mul(unity_ObjectToWorld, v.vertex).xyz;
2. o.buv = float4(worldPos.x + _CosTime.x * 0.2, worldPos.z + _SinTime.x *0.3 ,worldPos.x + _CosTime.y * 0.04, worldPos.z + o.bumpTexCoord.w )*0.05;

With this the water texture stay fix but the foam and speculation light continue to move. I had to do the same trick with them but I don't know how.

And in LOD5, uncomment the lines :

Code (CSharp):

1. //World UV's
2.                 o.worldPos = mul(unity_ObjectToWorld, v.vertex).xyz;  
3.                 o.bumpuv.xyzw = o.worldPos.xzxz  * _WaveTiling*0.005  + frac(_Time.xxxx * _WaveDirection);

Did do nothing.

Unfortunately my shader knowledge is very low ( something I have to learn ... ) and can't find any solutions to go further.

 

Let me make some modifications and I will sent you a shader in a pm.

 

Thanks for you help.
I starting to learn about shader in unity and I have found kind of a solution.
I've make a simple texture shader to train my self.
I fisrt calculate the world position like this in vert function:

Code (CSharp):

1. o.worldPos = mul(unity_ObjectToWorld, v.vertex)

Then use it with xz coordinates (take me a lot of time to understand I have to use xz coordinates ...) like this with the main texture in the frag function:

Code (CSharp):

1. col = tex2D(_MainTex, i.worldPos.xz)

I have to learn more about shaders to apply this to the community Ocean shader.

 

Ok I find a solution with the Ocean Community Shader but not completly ...
I stoped the textures to rotate and move with my mesh by calculating a world position:

Code (CSharp):

1. float3 worldPos = mul(unity_ObjectToWorld, v.vertex).xyz;

And apply it to the o.buv:

Code (CSharp):

1. o.buv = float4(worldPos.x + _CosTime.x * 0.2, worldPos.z + _SinTime.x * 0.3 ,worldPos.x + _CosTime.y * 0.04, worldPos.z + o.bumpTexCoord.w ) * 0.05;

Unfortunately the bumps and foam are no longer sliding a the surface ( even with the cos and sin calculation )
And the last thing I have to fix is the Specularity that is always rotating with my mesh so fix at screen.
I try to change the line:

Code (CSharp):

1. o.lightDir = mul(rotation, half3(_SunDir.xyz));

by:

Code (CSharp):

1. o.lightDir = half3(_SunDir.xyz);

But with that, the specular effect just disepear and I don't know how to manage this.
I'm close to my goal, If anyone have any idea thanks.

 

anyone was able to fix the shoreline? I haven't had one for over a year, since I don't even remember which unity version.

 

Have you seen this interesting presentation document from the team that made WarThunder. They are discussing some interesting techniques for doing onshore waves. http://developer.download.nvidia.co...vents/cgdc15/CGDC2015_ocean_simulation_en.pdf

 

yeah i have, but we are working on mobile and with the community ocean shader. That paper requires a full new system that I would be happy to pay for. Can you develop it? Otherwise, it's out of scope on this thread. The current system is perfect but it broke with unity updates. It had shore lines already implemented. Just nobody seems to know how to fix them on the newer version of unity.

 

Hey guys! Awesome implementation. I had two short questions:

1. It's open source and the license states you can do whatever but I wanted to be 100% sure this can be freely used in a commercial project.
2. What is the part of the shader code responsible for trail foam? The foam left behind as you move around.

Thanks!

 

Is it possible to add endless underwater to the library somehow?

 

Hi community, I understand the old branch. Can anyone know if it will work on openGL 3.0 and Vulkan? I'm doing a project on google cardboard.

 

Is there a version adapted for URP?
