Iirc for this you need a "custom editor GUI" script
Shader Graph's importable "production ready shaders" sample has an example of the Lit shader's custom GUI

aw man i didn't wanna have to do manual scripting for such as simple thing 😭

#

are there any alternatives?

meager apex Jul 21, 2025, 9:04 AM

#

None that I know of
Besides just to live with all properties visible

#

An editor GUI editor would be nice

rapid mountain well thanks, ill check it out

The way to get to it is probably like this, even without the sample

#

that looks like it's for HDRP, im using URP

#

idk if it matters, i just thought i'd point that out

#

oh found it

#

Graph Settings have "Custom Editor GUI" field which in the sample points to LitShader.cs that you can find by searching in "all" or "packages"

#

ye i saw that too

#

https://docs.unity3d.com/ScriptReference/ShaderGUI.html im using this as a reference too

#

i'll share my findings here when i figure it out

#

just for if someone happens to also have this issue

AH i did it

#

so first you make a boolean KEYWORD

#

not just a normal boolean

#

and by default it makes it into a branch kind of thing

#

in the shader gui script, i used this code

using System;
using UnityEditor;
using UnityEngine;

public class VertexColorTextureBlendEditor : ShaderGUI
{
    float doesThisWork = 0f;

    override public void OnGUI(MaterialEditor materialEditor, MaterialProperty[] properties)
    {
        base.OnGUI(materialEditor, properties);

        Material targetMat = materialEditor.target as Material;

        bool useMetallicMap = Array.IndexOf(targetMat.shaderKeywords, "_USEHEAVYMETALMAP_ON") != -1;

        if (useMetallicMap)
            doesThisWork = EditorGUILayout.FloatField("Does This Work?", doesThisWork);
    }
}

#

and yes you gotta do this

#

thank you @meager apex
