Mesh Tools - Mesh combiner and replacer System

This package enables combining multiple materials and meshes/skinned meshes into a single mesh/skinned mesh with a unified material. Merging optimizes rendering performance by reducing draw calls, but it's important to benchmark for optimal mesh setup. Skinned mesh merging supports submesh merging. Additionally, the package includes a mesh/skinned mesh replacer tool to replace the original renderer and materials with the selected skinned mesh renderer on the currently chosen model.
