Proxy Mesh
Generates a simplified mesh from selected occurrences. Commonly used in retopology workflows to create clean, optimized geometry for further processing such as baking materials or generating LODs.

API function: algo.proxyMesh
The Proxy Mesh feature remeshes selected meshes using a marching cubes technique to create a watertight mesh free of unnecessary internal parts, designed for lightweight performance.
The generated mesh can be used for mesh colliders and shadow meshes:
Combine with baking to create an optimized version of the input meshes that preserves their overall look, while simplifying less noticeable details to improve performance (it yields a single-material mesh, which minimizes draw calls) without sacrificing visual quality:
注
The Retopologize action in the Asset Transformer Toolkit demonstrates the combined use of the Proxy Mesh and Baking features.
The algorithm
This algorithm is based on marching cubes computed on a dilated voxel grid in order to create a watertight mesh.
To be compatible with surfacic meshes, a specific parameter exists, that will improve the quality of the reconstruction by allowing non-watertight meshes to be created, and avoided double-skin around surfacic meshes.
