Convert PCG to UVN

Understanding PCG and UVN file formats

PCG files are typically associated with graphics or pattern data, often used in retro gaming or embedded systems for storing tile or sprite graphics. The format is not standardized and may vary depending on the originating software or hardware platform.

UVN files, on the other hand, are less common and are usually related to 3D graphics, often representing vertex normal data or UV mapping information for textures in 3D models. The specifics of the UVN format can differ based on the application that uses it.

How to convert PCG to UVN

Since both PCG and UVN are niche formats, there is no universal, one-click converter available. Conversion typically requires understanding the structure of both file types and may involve custom scripting or specialized tools.

Here are the general steps for conversion:

1. Analyze the PCG file to extract the relevant graphics or pattern data.
2. Determine the required structure for the UVN file (e.g., vertex, normal, and UV mapping data).
3. Use a graphics or 3D modeling tool (such as Blender) to import the PCG data, if possible, or manually recreate the graphics as a 3D model.
4. Export the model or data in a format that supports UV and normal information, such as OBJ or FBX.
5. If a specific UVN format is required, use a custom script or converter to transform the exported data into the UVN structure.

Recommended software for conversion

Blender is a powerful, free, and open-source 3D modeling tool that can help with this process. You can:

• Import or recreate the graphics from the PCG file.
• Assign UV mapping and normals as needed.
• Export the model using File → Export → OBJ or File → Export → FBX.
• Use a custom script (Python is recommended) to convert the exported file to the required UVN format.

For scripting, Python is ideal due to its strong support for file parsing and manipulation.

Summary

Converting PCG to UVN is a specialized task that may require manual steps and custom scripting. Blender is the best tool for handling the 3D aspects, while Python can be used for file format conversion.
