MXS File Format Explained

The MXS format is the Maxwell Render scene file format. It is designed to store a complete 3D scene description, acting as a bridge between 3D modeling applications and the standalone Maxwell rendering engine.

MXS File Format Details What It Stores It contains comprehensive scene data including geometry, camera settings, Maxwell materials and material assignments, instancing data, and Multilight setup information. Textures used in materials and HDR/MXI textures used in the scene are referenced, not embedded. Primary Use Cases Transferring production-ready scenes to standalone render nodes or farms. Managing complex architectural visualization scenes with physically accurate lighting. Iterative lighting adjustments using Multilight technology by changing individual light intensities during or after rendering without rerendering the scene. Archiving finalized 3D assets with their specific material and lighting context. Strengths Maintains high fidelity of Maxwell physically based rendering parameters across Maxwell Render workflows. Can use referenced MXS files to reduce main scene file size and export time for repetitive or complex static geometry. Allows lighting adjustments during or after rendering when Multilight is enabled. Limitations Proprietary format is primarily intended for the Maxwell Render ecosystems. Files can become extremely large depending on scene complexity and embedded geometry. Common Software Support Primarily supported by Maxwell Render, Maxwell Studio, and Maxwell plugins for applications such as 3ds Max, Maya, Cinema 4D, Rhino, SketchUp, ArchiCAD, and formZ.
