Questions & Answers
LWS files: Frequently Asked Questions
What are LWS files?
LWS (LightWave Scene) is a file format used to store scenes created in NewTek's LightWave 3D software. It contains information about the objects, lights, cameras, and other elements that make up a 3D scene. The LWS format is used to save and share complete 3D scenes, allowing users to easily transfer their work between different projects or collaborate with other artists. Like the LWO format, LWS is widely used in film and television production, video game development, and architectural visualization.
