KIBAMaterialGUI

KIBAMaterialGUI is an attribute-driven Unity ShaderGUI for material inspectors. Shader authors describe layout and editor behavior with ShaderLab attributes, and KIBAMaterialGUI builds a grouped, searchable, resettable inspector from those hints.

Requires Unity 2022.3 or newer. This is an editor-only package with no VRChat SDK dependency.

Install

Install through VCC after adding the KIBALAB VPM listing:

https://vpm.kiba.red/vcc

For embedded development, add the package as a local Unity package:

{
  "dependencies": {
    "com.kibalab.kibamaterialgui": "file:../com.kibalab.kibamaterialgui"
  }
}

Quick Start

Add the custom editor to a shader:

CustomEditor "KIBA_.KIBAMaterialGUI.Editor.MaterialGUI"

Use ShaderLab attributes to drive layout and renderer hints:

Properties
{
    [Group(Basics)] _MainTex ("Main Texture", 2D) = "white" {}
    [Group(Basics)] _Tint ("Tint", Color) = (1,1,1,1)

    [Group(Advanced,Vectors)][Vector(2)] _UV ("UV Transform", Vector) = (1,1,0,0)
    [Group(Advanced,Lighting)][Toggle] _LightingToggle ("Lighting", Float) = 0
    [Group(Advanced,Lighting)][ShowIf(_LightingToggle, 1)] _ShadowColor ("Shadow Color", Color) = (0,0,0,1)
}

Nested group paths use comma-separated [Group(...)] arguments. Slash parsing and display-name layout fallback are intentionally not supported.

Attribute Highlights

• [Group(Name)] and [Group(Parent,Child)] route properties into groups.
• [ShowIf(_Prop)] and [ShowIf(_Prop, value)] hide dependent properties until a numeric controller matches.
• [Vector(2)], [Vector(3)], [Vector(4)] control vector field count.
• [MinMaxSlider(min, max)] renders a vector as a min/max range.
• [Unit(label)], [Divider], [Space(px)], [SegmentedEnum], and [GradientTexture] add focused UI hints.
• Unity attributes such as [Enum], [KeywordEnum], [Toggle], [ToggleOff], [HDR], and [NoScaleOffset] remain supported.

Custom Renderers

Custom property renderers are auto-discovered by TypeCache:

using KIBA_.KIBAMaterialGUI.Editor.UI.Property;
using UnityEditor;
using UnityEngine;

[MaterialGUIPropertyRenderer(
    Order = -100,
    PropertyTypes = new[] { MaterialProperty.PropType.Float },
    RequireShaderAttributes = new[] { "MyHint" })]
public sealed class MyHintRenderer : IMaterialGUIPropertyRenderer
{
    public float GetHeight(PropertyRendererArgs args)
        => EditorGUIUtility.singleLineHeight;

    public Rect OnGUI(PropertyRendererArgs args)
    {
        EditorGUI.BeginChangeCheck();
        var next = EditorGUI.FloatField(args.Position, args.Label, args.Property.floatValue);
        if (EditorGUI.EndChangeCheck())
            args.SetFloatValue(next);
        return args.Position;
    }
}

Use PropertyRendererArgs.SetFloatValue, SetIntValue, SetColorValue, SetVectorValue, SetTextureValue, SetTextureScaleAndOffset, or RegisterPropertyValueChange before manual writes. Call setters inside a change check so repainting does not overwrite mixed selections. These helpers keep undo and Unity animation recording behavior consistent.

Editor-level extensions can also use:

• IShaderEditor with [ShaderEditorInjection(...)] for low-level hook drawing.
• IMaterialGUIGroupActionContributor for group header actions and drag start behavior.
• IMaterialGUIDiagnosticProvider for shader/property diagnostics.
• IMaterialGUIFilterProvider for custom toolbar filters.

Extension callbacks receive a read-only MaterialGUIContext.

Known Limitations

• Animation keyframe context menu actions rely on Unity editor internals and are best-effort.
• Conditional visibility v1 supports numeric comparisons only.
• This preview release may still make breaking API changes.

See Website~/docs/ for the quickstart, attribute reference, inspector guide, presets/localization guide, custom renderer guide, editor injection guide, Scripting API, and troubleshooting notes.

Samples

The package includes Samples/AllElementsDemo, a large shader that exercises groups, filters, conditional visibility, presets, localization, validation, custom renderers, and editor contributions.
