HDR Light Studio 

Create lighting patterns in high definitions for 3D modeling projects. Access the settings of a selected object and automatically or manually generate various environment maps with custom light sources and shading in real time. Render interactive scenes.

HDR Light Studio lets you easily create and edit HDRI environment maps in real-time. As you develop your custom HDRI map you see its lighting effect in real-time on your 3D scene -- either by using HDR Light Studio connected 'Live' to your 3D app or using it standalone with the included interactive renderer -- LiveLight.
