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:
Remeshing
 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:

Note
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.
