How to make Ocean in Unity 3D

Hello everyone,
I need to create from 0 an Ocean in Unity 3D.
I'm starting with Unity and I do not understand very well the concept of Shader or where to look for this type of Assets in the store.

On the other hand, I need information on how to make an ocean (with waves) and with a marine part (diving).
If someone can pass me useful links (tutorial, guides, ...) I appreciate it.

Thank you.

PS: I do not know if this post is in this section, if not, move it please. Thanks again.

 

Check the asset store... there are tons of great ocean and water assets there.

 

some resources:

using shader graph editor (no need to write shader code yourself)
https://blogs.unity3d.com/2018/10/05/art-that-moves-creating-animated-materials-with-shader-graph/

shader coding basics,
https://unity3d.com/learn/tutorials/topics/graphics/gentle-introduction-shaders

quick start wavy mesh
see example "Normal Extrusion with Vertex Modifier"
then modify how the vertex are moved to make it look wavy
https://docs.unity3d.com/Manual/SL-SurfaceShaderExamples.html
see some helper variables from here https://docs.unity3d.com/Manual/SL-UnityShaderVariables.html
like _CosTime.x to make your vertices move
