+AniGen represents shape, skeleton, and skinning as mutually consistent $S^3$ Fields (Shape, Skeleton, Skin) defined over a shared spatial domain. Built upon a two-stage flow-matching pipeline, it first synthesizes a sparse structural scaffold and then generates dense geometry and articulation in a structured latent space.

 ## Recommended Checkpoints
 
 For most users, we recommend:
-
-- `ss_flow_duet` for sparse structure generation
-- `slat_flow_auto` for structured latent generation
-
-This combination is also the default setup used by the AniGen inference example.

-## Notes
-
-- Keep the directory names unchanged. The AniGen code expects the exact `ckpts/...` layout shown above.
-- The code repository may automatically fetch missing files in some setups, but this weights repository is the recommended way to pre-download and manage checkpoints explicitly.
-- `slat_flow_control` supports joint density control, while `slat_flow_auto` is the best default for general use.
