September 2025 — Momentum (facebookresearch/momentum) focused on a targeted performance optimization for applySSD through configurable threading. Implemented exposure of the maximum number of threads for applySSD and introduced workload-aware parallelization using dispenso::ParForOptions, with minItemsPerChunk set to 1024u to guide thread allocation based on workload. This enables dynamic thread management and better utilization of multi-core environments. Change integrated under commit 9306d80deed32b73c12b69c4f5d4ae67fcc7dd9e (Expose max threads in applySSD, #616).

June 2025: Stabilized Momentum's FBX importer by correctly handling per-vertex vs per-face UV mappings in loadFbx. Introduced conditional logic and validations to prevent runtime errors, and added test FBX files to verify both mapping types. Linked to issue #379. Result: more robust data import and improved reliability for downstream experiments in training and evaluation workflows.

April 2025 monthly summary for facebookresearch/momentum focused on expanding model import capabilities and reducing asset ingestion errors. Key achievement was delivering robust FBX importer support for non-skinned models by deferring SkinWeights creation until skinning data is present, enabling import of non-skinned assets and improving pipeline resilience. This work reduces importer failures and broadens asset compatibility, delivering business value for researchers and content pipelines that rely on diverse FBX assets. No separate critical bugs opened this month; the primary impact stems from feature delivery and code quality improvements evidenced by the committed changes. Technologies demonstrated include FBX parsing, defensive data handling, and asset pipeline integration, with strong emphasis on maintainability and scalable imports.
