🚀 Getting Started

🚀 Getting Started

1️⃣ Add the CustomUI Component

1. Select a UI component in Unity (e.g., Image, TextMeshProUGUI)
2. Open the Inspector panel
3. Click Add Component and search for UIMaterialModifier

2️⃣ Assign a Shader

1. Ensure the UI component's Material uses a shader that supports modification.
2. Example: UI/Unlit/Transparent

3️⃣ Modify Shader Parameters

You can modify properties directly in the Inspector:

• Color (_Color)
• Transparency (_Alpha)
• Saturation (_Saturation)
• Contrast (_Contrast)

Or modify them via script:

using Dennis.UI;

CustomUI customUI = myGameObject.GetComponent<CustomUI>();
customUI.SetFloat("_Saturation", 1.5f);
customUI.SetColor("_Color", Color.red);

⚠️ Shader Property Not Found Warning

🔹 Why Does This Happen?

If you enter a property name that does not exist in the shader, you will see a yellow warning in the Inspector:

Shader does not have property 'aaa'

🔹 How to Fix This Issue

1️⃣ Check the Shader Property Name

• Open the Material Inspector and find the exact property name.
• Ensure it starts with _ (e.g., _Color, _Saturation).

2️⃣ Verify That the Shader Supports the Property

• Open the Shader Code (.shader file) and check if the property exists.
• Example:

  _Saturation ("Saturation", Range(0, 2)) = 1

• If the shader does not define _Saturation, adding it in UIMaterialModifier will have no effect.

3️⃣ Use the Correct Property Type

Property Name	Expected Type	Incorrect Type
_Color	Color	Float, Int
_Saturation	Float	Color, Vector4

⚠️ Shader Property Type Mismatch Warning

🔹 Why Does This Happen?

If you select a shader property type that does not match the actual property type, you will see a yellow warning in the Inspector:

Shader property '_Color' is expected to be Color, but you assigned Float.

🔹 How to Fix This Issue

1️⃣ Check the Shader Property Type

• Click on the Material attached to your UI element.
• Find the shader property you want to modify.
• Verify its type in the shader code (e.g., _Color should be Color, _Saturation should be Float).

2️⃣ Select the Correct Type in the Inspector

• If _Color is a Color, select Color from the dropdown.
• If _Saturation is a Float, select Float from the dropdown.

3️⃣ Fix it in the Inspector

• ✅ Before (Wrong)
  • Property Name: "_Color" Type: Float 🚨 Warning: Shader property '_Color' is expected to be Color, but you assigned Float.
• ✅ After (Fixed)
  • Property Name: "_Color" Type: Color ✅ No Warning

🔹 Best Practices

• ✅ Always check the shader property type before modifying it.
• ✅ Use Inspector > Material to confirm available properties.
• ✅ Only modify properties that exist in the shader.
• ✅ Use a test material to verify property changes before applying them globally.
