[Shader Graph] - Creating a custom node based on 3d noise

Hi guys,

For a project I needed to realise a blob to do that I use Unity's Shader graph feature. I apply a random ( actually 2d noise ) transformation on vertex position. Everything work correctly but I've got a mirror effect on my blob due to 2d noise.

Not a big deal, I just need to replace it by a 3d noise but there is no 3d noise node in Shader graph. I've decided to create a custom one. I read documentation about custom node and I decided to use this 3d noise into my custom node.

I copy / paste the 3d noise into that method :

Code (CSharp):

1.  
2. static string MyCustomFunction(
3.         [Slot(0, Binding.None)] DynamicDimensionVector A,
4.         [Slot(1, Binding.None)] DynamicDimensionVector B,
5.         [Slot(2, Binding.None)] out DynamicDimensionVector Out)
6.     {
7.         return @"
8.        {
9.            // Here is where I copy / pasted the code <----------
10.        }
11.        ";
12.     }
13.  

Obviously that didn't work.

I've realised I can't declare functions in this return so I tried to split the 3d noise code but without success. I check the custom node doc and I didn't find any complex exemple -Just some easy exemple like how to add two input together-.

If someone know where I can find further example / documentation about custom node in shader graph I will be thankful.
