LWGUI (Light Weight Shader GUI)

中文 | English

A Lightweight, Flexible, Powerful Unity Shader GUI system.

Having been validated through numerous large-scale commercial projects, employing a succinct Material Property Drawer syntax allows for the realization of powerful Shader GUIs, substantially reducing development time, fostering ease of use and extensibility, and elevating the user experience for artists effectively.

NEW: A more powerful Gradient editor than UE, with support for both Shader and C#	NEW: Insert images directly into the ShaderGUI to support the display of complex documents without having to jump to the browser
The search bar can also filter for properties that have been modified	Right-click to paste the attribute value by type

Installation

1. Make sure your environment is compatible with LWGUI

   • LWGUI <1.17: Unity 2017.4+

   • LWGUI >=1.17: Unity 2021.3+

     • Recommended minimum version: Unity 2022.2+, lower versions can be used but may have bugs

2. Open your project

3. Window > Package Manager > Add > Add package from git URL , enter: https://github.com/JasonMa0012/LWGUI.git

   • You can also choose to manually download the Zip from Github，then: Package Manager > Add package from disk
   • For Unity 2017, please extract the Zip directly to the Assets directory

Usage

Getting Started

1. Create a newer or use the existing Shader
2. Open the Shader in the code editor
3. At the bottom of the Shader, before the last large bracket, add line:CustomEditor "LWGUI.LWGUI"
4. Completed! Start using the following powerful Drawer to easily draw your Shader GUI
   • MaterialPropertyDrawer is C#-like attribute syntax, it can be used in front of shader properties to change the drawing method, more information can be found in the official documentation: https://docs.unity3d.com/ScriptReference/MaterialPropertyDrawer.html
   • Each Property can only have one Drawer
   • Each Property can have multiple Decorators

LWGUI Drawers

Main & Sub

/// Draw a property with default style in the folding group
/// group: father group name, support suffix keyword for conditional display (Default: none)
/// Target Property Type: Any
public SubDrawer() { }
public SubDrawer(string group)

Example:

Result:

Channel

/// Draw a R/G/B/A drop menu:

/// group: father group name, support suffix keyword for conditional display (Default: none)
/// Target Property Type: Vector, used to dot() with Texture Sample Value 
public ChannelDrawer() { }
public ChannelDrawer(string group)

Example:

[Title(_, Channel Samples)]
[Channel(_)]_textureChannelMask("Texture Channel Mask (Default G)", Vector) = (0,1,0,0)

......

float selectedChannelValue = dot(tex2D(_Tex, uv), _textureChannelMask);

Ramp

ShaderLab

/// Draw an unreal style Ramp Map Editor (Default Ramp Map Resolution: 512 * 2)
/// NEW: The new LwguiGradient type has both the Gradient and Curve editors, and can be used in C# scripts and runtime, and is intended to replace UnityEngine.Gradient
/// group: father group name, support suffix keyword for conditional display (Default: none)
/// defaultFileName: default Ramp Map file name when create a new one (Default: RampMap)
/// rootPath: the path where ramp is stored, replace '/' with '.' (for example: Assets.Art.Ramps). when selecting ramp, it will also be filtered according to the path (Default: Assets)
/// colorSpace: switch sRGB / Linear in ramp texture import setting (Default: sRGB)
/// defaultWidth: default Ramp Width (Default: 512)
/// viewChannelMask: editable channels. (Default: RGBA)
/// timeRange: the abscissa display range (1/24/2400), is used to optimize the editing experience when the abscissa is time of day. (Default: 1)
/// Target Property Type: Texture2D
public RampDrawer() : this(String.Empty) { }
public RampDrawer(string group) : this(group, "RampMap") { }
public RampDrawer(string group, string defaultFileName) : this(group, defaultFileName, DefaultRootPath, 512) { }
public RampDrawer(string group, string defaultFileName, float defaultWidth) : this(group, defaultFileName, DefaultRootPath, defaultWidth) { }
public RampDrawer(string group, string defaultFileName, string rootPath, float defaultWidth) : this(group, defaultFileName, rootPath, "sRGB", defaultWidth) { }
public RampDrawer(string group, string defaultFileName, string rootPath, string colorSpace, float defaultWidth) : this(group, defaultFileName, rootPath, colorSpace, defaultWidth, "RGBA") { }
public RampDrawer(string group, string defaultFileName, string rootPath, string colorSpace, float defaultWidth, string viewChannelMask) : this(group, defaultFileName, rootPath, colorSpace, defaultWidth, viewChannelMask, 1) { }
public RampDrawer(string group, string defaultFileName, string rootPath, string colorSpace, float defaultWidth, string viewChannelMask, float timeRange)

Example:

[Ramp(_, RampMap, Assets.Art, 512)] _Ramp ("Ramp Map", 2D) = "white" { }

Result:

You must manually Save the edit results, if there are unsaved changes, the Save button will display yellow.

When you move or copy the Ramp Map, remember to move together with the .meta file, otherwise you will not be able to edit it again!

C#

Example:

public class Test : MonoBehaviour
{
    public LwguiGradient lwguiGradientSrgb = new LwguiGradient();

    [LwguiGradientUsage(ColorSpace.Linear, LwguiGradient.ChannelMask.RGB, LwguiGradient.GradientTimeRange.TwentyFourHundred)]
    public LwguiGradient lwguiGradientLinear = new LwguiGradient();
}

Result:

Default display settings can be set using the LwguiGradientUsage() Attribute.

Gradient Editor

The new LWGUI Gradient Editor integrates with Unity's built-in Gradient Editor and Curve Editor, enabling more powerful features than UE's Gradient Editor.

Known issues:

• Preview images below Unity 2022 have no difference between sRGB/Linear color spaces
• Ctrl + Z results may be slightly different from expected when the editor frame rate is too low

Preset

/// Popping a menu, you can select the Shader Property Preset, the Preset values will replaces the default values
/// group: father group name, support suffix keyword for conditional display (Default: none)
///	presetFileName: "Shader Property Preset" asset name, you can create new Preset by
///		"Right Click > Create > LWGUI > Shader Property Preset" in Project window,
///		*any Preset in the entire project cannot have the same name*
public PresetDrawer(string presetFileName) : this("_", presetFileName) {}
public PresetDrawer(string group, string presetFileName)

Example:

[Title(Preset Samples)]
[Preset(LWGUI_BlendModePreset)] _BlendMode ("Blend Mode Preset", float) = 0 
[Enum(UnityEngine.Rendering.CullMode)]_Cull("Cull", Float) = 2
[Enum(UnityEngine.Rendering.BlendMode)]_SrcBlend("SrcBlend", Float) = 1
[Enum(UnityEngine.Rendering.BlendMode)]_DstBlend("DstBlend", Float) = 0
[Toggle(_)]_ZWrite("ZWrite ", Float) = 1
[Enum(UnityEngine.Rendering.CompareFunction)]_ZTest("ZTest", Float) = 4 // 4 is LEqual
[Enum(RGBA,15,RGB,14)]_ColorMask("ColorMask", Float) = 15 // 15 is RGBA (binary 1111)
    
``````
    
Cull [_Cull]
ZWrite [_ZWrite]
Blend [_SrcBlend] [_DstBlend]
ColorMask [_ColorMask]

Result:

The Property Value in the selected Preset will be the default value

RenderQueue is a Hard-Coded Property Name, you need to manually add it to the preset

Create Preset File

Tips:

• Tooltip may disappear when the Editor is running. This is a feature of Unity itself (or a bug)

/// headerString: The title of the Advanced Block. Default: "Advanced"
public AdvancedDecorator() : this(string.Empty) { }

[Advanced][Sub(Group2)] _Advancedfloat4 ("Advanced Float 4", float) = 0
[AdvancedHeaderProperty][Tex(Group2, _Advancedfloat7)] _AdvancedTex0 ("Advanced Header Property Test", 2D) = "white" { }
[Advanced][HideInInspector] _Advancedfloat7 ("Advanced Float 7", float) = 0
[Advanced][Tex(Group2, _AdvancedRange0)] _AdvancedTex1 ("Advanced Tex 1", 2D) = "white" { }
[Advanced][HideInInspector] _AdvancedRange0 ("Advanced Range 0", Range(0, 1)) = 0

Tips:

• LWGUI uses a tree data structure to store the relationship between Group, Advanced Block and their children. In theory, it can store unlimited multi-level parent-child relationships, but currently LWGUI only manually handles 3-level parent-child relationships, which means you can put an Advanced Block in a Group, but a Group cannot be placed in an Advanced Block.

Custom Shader GUI

Custom Header and Footer

1. Custom Headers and Footers enable you to integrate bespoke modules at the top or bottom of the ShaderGUI without altering LWGUI plugin code.

2. Depending on the desired location for the custom GUI, duplicate the following script into an Editor folder within your project:

   • Top: Packages/com.jasonma.lwgui/Editor/CustomGUISample/CustomHeader.cs
   • Bottom: Packages/com.jasonma.lwgui/Editor/CustomGUISample/CustomFooter.cs

3. Modify the file name and class name accordingly.

4. Implement your custom GUI code within the DoCustomHeader() / DoCustomFooter() functions.

5. It is advisable to examine the lwgui object definition to obtain any requisite data.
