 ## Using the Inspector
 
 Using the Inspector allows you to change all of the Decal Projector properties, and lets you use numerical values for **Size**, **Tiling**, and **Offset**, which allows for greater precision than the click-and-drag gizmo method.
 
 ## Properties

 | **Property**            | **Description**                                              |
 | ----------------------- | ------------------------------------------------------------ |
 | **Size**                | The size of the projector influence box, and thus the decal along the projected plane. The projector scales the decal to match the **Width** (along the local x-axis) and **Height** (along the local y-axis) components of the **Size**. |
 | **Projection Depth**    | The depth of the projector influence box. The projector scales the decal to match **Projection Depth**. The Decal Projector component projects decals along the local z-axis. |
+| **Pivot**               | The offset position of the transform regarding the projection box. To  rotate the projected texture around a specific position, adjust the **X** and **Y** values. To set a depth offset for the projected texture, adjust the **Z** value. |
 | **Material**            | The decal Material to project. The decal Material must use a HDRP/Decal Shader. |
 | **Decal Layer**         | The layer that specifies the Materials to project the decal onto. Any Mesh Renderers or Terrain that uses a matching Decal Layer receives the decal. |
 | **Draw Distance**       | The distance from the Camera to the Decal at which this projector stops projecting the decal and HDRP no longer renders the decal. |
