 You can adjust the project-wide settings for UIEffect. (`Edit > Project Settings > UI > UIEffect`)
 
 - **Transform Sensitivity**: `Low`, `Medium`, `High`
   - Set the sensitivity of the transformation when `Use Target Transform` is enabled in `UIEffectReplica` component.
 - **Runtime Presets**: A list of presets that can be loaded at runtime. Load them using `UIEffect.LoadPreset(presetName)` method.
-- **Fallback Variant Behavior**: Specifies the behavior when an unregistered shader variant is used in the editor.
-  - `Register Variant`: Adds the variant to `Registered Variants` for runtime use.
-  - `LogError`: Outputs a error and adds it to `Unregistered Variants`.
+- **Optional Shaders (UIEffect)**: A list of shaders that will be prioritized when a ui-effect shader is
+  requested.
+    - If the shader is included in the list, that shader will be used.
+    - If it is not in the list, the following shaders will be used in order:
+        - If the shader name contains `(UIEffect)`, that shader will be used.
+        - If `Hidden/<shader_name> (UIEffect)` exists, that shader will be used.
+        - As a fallback, `UI/Default (UIEffect)` will be used.
+- **Registered Variants**: A list of shader variants available at runtime. Use "-" button to remove unused variants,
+  reducing build time and file size.
+    - By default, the used ui-effect shaders will be included in the build. You can remove them if you don't need.
 - **Unregistered Variants**: A list of shader variants that are not registered. Use "+" button to add variants.
-- **Registered Variants**: A list of shader variants available at runtime. Use "-" button to remove unused variants, reducing build time and file size.
+- **Error On Unregistered Variant**: If enabled, an error will be displayed when an unregistered shader variant is used.
+    - The shader variant will be automatically added to the `Unregistered Variants` list.
