 Overrides determine which Wearable categories or avatar body parts your item will hide. For instance, a hat with attached hair might need to hide the _Hair_ category. A deep-sea diver helmet may require hiding head accessories like earrings, eyewear, tiaras, etc., which wouldn’t be visible. Multiple options can be selected for each override.

 - **Base Body**: This refers to core avatar parts like the _head_ and _hands_. For example, if you’re creating a **Handwear** item such as a robot mechanic hand, you’ll likely need to hide _hands_ to prevent overlap and clipping.
 
 - **Wearables**: This includes other Wearable categories. You can hide multiple categories. For more details on each category and how items interact, refer to **[Creating Wearables](https://docs.decentraland.org/creator/wearables/creating-wearables/)**.

 When this property is enabled, it will allow owners of your item to include it in VRM Avatar Exports so they can show it off outside of Decentraland.
 
+## **Outline**
+
+The Outline toggle controls whether your wearable is compatible with Decentraland's outline rendering system (used in Medium/High quality settings). By default, this is enabled for all new wearables.
+
+You should disable this option if your wearable:
+- Has manually created outlines in the model
+- Uses inverted normals
+- Shows visual artifacts when the outline effect is applied
+
+Most wearables work fine with the default setting (enabled). Only disable this if you notice outline-related visual issues with your wearable. Once you disable the outline, you will need to save the changes by clicking on **_Save_**.

 ## **Adding Another Representation**
 
 If your wearable has a different representation for male and female you will need to upload another file. So far, you only have one uploaded. In the example, it was the female version of the Krampus Sweater. To add the other representation, click on the three dots (_…_) at the top right, next to **_Properties_** and select **_Add male/female_** representation. In the example below, we needed the male version.
