Convert OBJ to MIX

Understanding OBJ and MIX file formats

OBJ is a widely used 3D model format developed by Wavefront Technologies. It stores 3D geometry, including the position of each vertex, the UV position of each texture coordinate vertex, normals, and the faces that make each polygon. OBJ files are popular in 3D graphics applications due to their simplicity and compatibility.

MIX is a proprietary file format used primarily by Westwood Studios for games like Command & Conquer. MIX files are archive containers that store various game assets, such as graphics, sounds, and 3D models. Converting OBJ to MIX is typically required for modding or custom content creation in these games.

How to convert OBJ to MIX

Converting an OBJ file to a MIX file is not a straightforward process, as MIX is an archive format rather than a direct 3D model format. The process usually involves converting the OBJ model into a format compatible with the game (such as SHP or VXL for Command & Conquer), and then packaging it into a MIX archive.

Recommended software for OBJ to MIX conversion

• XCC Mixer: This is the most popular tool for working with MIX files. It allows you to create, extract, and manage MIX archives. However, it does not convert OBJ files directly; you must first convert your OBJ to a supported format (like SHP or VXL) using other tools.
• OS SHP Builder: Use this tool to convert 3D models (after rendering or rasterizing them) into SHP format, which can then be added to a MIX archive.
• VXLSE III: For voxel-based models, convert your OBJ to VXL format, then use XCC Mixer to package it into a MIX file.

Step-by-step conversion process

1. Convert your OBJ file to a game-compatible format (such as SHP or VXL) using OS SHP Builder or VXLSE III.
2. Open XCC Mixer.
3. Use File → New to create a new MIX archive.
4. Add your converted asset (SHP or VXL file) to the archive using Insert or drag-and-drop.
5. Save the archive as a .MIX file using File → Save As.

Tips and considerations

• Ensure your OBJ model is properly optimized and compatible with the target game's requirements before conversion.
• Some manual adjustments may be needed during the conversion to SHP or VXL formats.
• Always test your MIX file in the game environment to verify correct integration.
