    Hey Guys,


    im trying to create a Standard Surface Shader for my mesh.
    I have a custom shader with very simple code:

    Code (CSharp):
    1.         void surf (Input IN, inout SurfaceOutputStandard o)
    2.         {
    3.             o.Albedo = float3(0, 1, 0);
    4.         }
    its setting everything to green.

    But if i have my material using it, it just show the fallback pink color.



    Is there something im missing?

    If you need more information just ask. Im not quite sure which informations are all necessary.

    Surface shaders are no longer a thing in URP/HDRP.

    Your best bet is to use Shader Graph instead.

    Hey awesome for you answer. But im totaly lost with the graph.

    Im Currently trying to follow this tutorial:


    and Trying to transcript the Surface Shader to a Unlit Shader Graph:

    So far my results in the Picture.

    Im getting minHeight and maxHeight from the Material(this is working in the Material its set minHeight = 0, maxHeight = 93)

    And i added a Position node to get the world position. Hopefully for every Pixel? Im not quite sure what he is returning.

    Afterwards i have the custom function:
    Code (CSharp):
    1. result = saturate((value.y-a)/(value.y-b));
    which should give me a float value in a range based on my pixel height.

    Then im setting the color. It should end in a way that my low surface on a mesh are black and my uperonce getting somewhere close to white.

    Result is everything is just black.

    Im a bit quite lost with the Graph. I try the "Tutorial" but i would like to have a quick approach for my fairly easy task. Before i do a deep dive into shader graph.

    Can someone give my some hints?
    What am i missing and is this Shader Graph called like the old Surface Shader every time?

    I realized on the next step he blended between the colours. While this isn't as nice as his (blend distances) it does blend between the colours:

    Does anyone know how to do this with the textures?

    I figured it out and made a youtube tutorial that describes the process as well as has a download for a working Unity project:

    I hope this helps.

    The names are different in URP.

    You can look here to see that the new shader name is.

    if you add a inverse lerp with the minHeight and maxHeight and the world y position, after the split you can work with the values that are in the video

    There's also Better Shaders, which is a surface shader replacement system for all pipelines. It's pretty easy to convert existing surface shaders over if graph's aren't your thing or you find you hit the limits of the shader graph.
