Exporters are plug-ins for 3D Applications which translate the scene into a format that can be read and rendered by LuxRender.

Most exporters also provide some sort of GUI for setting up Lux-specific settings in your scene, such as materials, textures and rendering settings.

LuxRender has exporters available for the following 3D Applications:

Blender	Autodesk Maya	Autodesk 3Ds Max	Maxon Cinema 4D	SoftImage XSI
