# Z-index An important concept for making elements feel immersive is where the **z-index** is set. A good rule of thumb is to set it right where the "ground" should be for that image. To edit the z-index, you can select your object and directly modify it with the red z-index line.

When a player is **above** the z-index line, they will appear **behind** the element.

By placing the z-index near the top of an element, you can create elements that players can walk entirely on top of; this will make them appear as though they are flat on the ground.

Placing the z-index low at the base of the element will make the element appear as if it is sitting in the world.

When editing elements, getting the z-index set correctly will make your world feel more immersive and alive. We recommend playing around with it until it feels right for each element. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
