"The resulting data can be used to render meshes using NVidia programmable mesh shading pipeline, or in other cluster-based renderers.", OK, I saw that. tks~

Thanks for your answer. Do you use the function meshopt_buildMeshlets or meshopt_buildMeshletsBound? When the demo was released, I saw that mesh shaders feature was not supported in MSL. Or you only use the lib to do vertex fetch optimize? Also for k-means, how do you configure the number of clusters for one mesh. ahhh... I see that the number of vertices in a mesh chunk is about 1000。
