Unreal dev created their own auto retopology tech
I've recently launched an auto retopology tool for Blender which I have been working on for over a year, it uses specialized methods for each mesh class (cloth, inanimate and organic) in order to reach the best possible output. Most of the time was spent in learning ONNX and how to build models correctly.
Inanimate objects can translate to any hard surface models which require no vertex deformation, the remesher is equipped to generate the lowest possible vertex count while prioritizing the overall 3D shape and outputting coherent edge flow mimicking artist-like topology.
Inanimate remeshing is completely automated and can handle loose parts intelligently, though it is recommended to keep face count below 1.1 mil to ensure a faster completion rate.
As for cloth remeshing, it is guided using UV islands while assisting the artist by highlighting the vertices to use for creating a grid. I plan to fully automate this using multiple AI layers + algorithms, much like what is currently configured for inanimate.
Documentation and tutorials are planned (things are pretty self explanatory though), will be visible in the account center under the Community section.
