Why not shader graph on water shader?

[RobertoPelonara]

I think one of the best way of learning something like shader graph is by analyzing how shaders are composed.

I followed a tutorial on YT of making shader graph water and I'm pretty happy with the result, but that tutorial is pointing me here with no water shader graph.

So the two main reasons it has yet to be ported are:

• There is no way to do a for loop in shadergraph, this is needed for custom lighting with additional lights(nicely) and also the softer shadows on the water
• No way to do vertex only calculations and pass that as custom data to the fragment(pixel) shader, right now since the water mesh is fairly dense for the wave displacement, a lot of shader calcuations can be done vertex only which saves a ton of processing

There are a few smaller issues stopping me from converting it over fully, at the end of the day, a water shader is quite complex and current shadergraph doesnt give you enough fine grained control over the little details in shaders, custom shader states, extra/custom passes, tesselation. There is work being done to address these so I'm looking forward to being able to convert it over one day.

Saying that there are a few shader graphs in this project to look at, cliffs, vegetation, boat colouring, clouds(wip) are a few, and I will be adding more as I finish off this project.
