ProMeshCombiner

The Mesh Combiner Tool provides a straightforward, customizable script for combining multiple meshes in a prefab into a single, optimized mesh asset. This tool is ideal for developers looking to improve rendering performance by reducing draw calls and organizing complex prefabs. It’s especially useful in performance-intensive projects, such as large-scale environments or high-detail scenes, where draw call reduction is essential.

This tool is easy to integrate into any Unity project without additional dependencies. Simply add the script to your project’s Editor folder, select a prefab, and run the tool from the Unity menu. The tool will automatically combine all meshes (including support for SkinnedMeshRenderers in static form) while preserving material configurations as submeshes.
