Open Light v0.1.0 Beta for Blender

Generate professional HDR light textures in seconds. No photography, no scanning – just pure procedural control.

Open Light is a standalone desktop tool that creates physically-plausible light modifier textures as 32-bit EXR files, ready to drop into Nuke, Houdini, Blender, Maya, 3ds Max, Unreal Engine, or any renderer that supports HDR lighting.
