# What is an Hemispheric Light? A **hemispheric light** is an easy way to simulate an ambient environment light. In our case, we are doing the bare minimum, just giving a name to the light and set it's location. Setting y location to 1 while our main object is in the center (0,0,0) location will move the light above the object. --- # 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.
