Isaac Sim Tips & Useful Links¶
Using a Dome Light¶
Using a Dome Light provides a natural-looking lighting environment to the scene. From the Create menu select Light > Dome Light. From the Property menu, you can specify a 4k texture by selecting your desired .hdr file in the “Texture File” field. Then, adjust the Dome Light’s Intensity. Decreasing the intensity for example, will make the lighting appear less harsh.
Tuning Real Time Mode’s Settings¶
Enable Sampled Direct Lighting¶
Under the RTX Settings tab, select the Ray Tracing category. By default, the “Enable Sampled Direct Lighting” checkbox will be empty.

Loading stages faster with Omniverse Cache¶
The first time you load a large stage, it may take a while for the materials to compile. Installing Omniverse Cache will help load the stage more quickly each subsequent time.
