Shader Utils for SRP v2

Utilities for SRP shaders.

Requirements

• Unity >= 2021.3.
• Core RP Library >= 12.0.0.

File Extensions

Create HLSL and SRP Shader files easily using menu item.

Preference Settings

Settings can be found in Preferences/Shader Utils for SRP.

Advanced Shader GUI

Use StaloSRPShaderGUI as CustomEditor.

CustomEditor "StaloSRPShaderGUI"

Advanced Shader Property Attributes

• HeaderFoldout(label[, ...tooltips])

  Begin an animated foldout header.

• Indent([count])

  Add indents before the property. The default count is 1.

• HelpBox(None|Info|Warning|Error, ...messages)

  Display a HelpBox above the property.

• PostHelpBox(None|Info|Warning|Error, ...messages)

  Display a HelpBox under the property.

• MinMaxRange(min-limit, max-limit)

  Display a vector property with a MinMaxSlider.

  • property.x: Min value.
  • property.y: Max value.

• RampTexture

  Display a texture as a ramp texture (similar to a color gradient).

• SingleLineTextureNoScaleOffset([color-property])

  Display a texture property in single line without Tiling and Offset. If color-property is specified, an additional color field will be displayed next to the texture.

• TextureScaleOffset

  Display a vector property as the Tiling and Offset of a texture.

  • property.xy: Tiling (Scale).
  • property.zw: Offset.

• If(expr)

  Display the property if expr evaluates to true. You can write complex expression like ((not _KEYWORD_A and true) or (_KEYWORD_B and not not not false)) and not _KEYWORD_C.

  Operator precedence: not > and > or.

Material Property Wrapper

This is similar to Unity's MaterialPropertyDrawer.

You can write a custom class inherited from MaterialPropertyWrapper (in namespace Stalo.ShaderUtils.Editor) to control the GUI of a material property.

Here's an example:

internal class PostHelpBoxWrapper : MaterialPropertyWrapper
{
    private readonly MessageType m_MsgType;
    private readonly string m_Message;

    public PostHelpBoxWrapper(string rawArgs) : base(rawArgs)
    {
        string[] args = rawArgs.Split(',', StringSplitOptions.RemoveEmptyEntries);

        for (int i = 0; i < args.Length; i++)
        {
            args[i] = args[i].Trim();
        }

        m_MsgType = Enum.Parse<MessageType>(args[0]);
        m_Message = string.Join(", ", args[1..]);
    }

    public override void OnDidDrawProperty(MaterialProperty prop, string label, MaterialEditor editor)
    {
        EditorGUILayout.HelpBox(m_Message, m_MsgType);
    }
}
