Complete Phase 2: Complex type support for USDC writer
🎉 Phase 2 COMPLETE - All USD composition and metadata types now supported! Features implemented: - Dictionary (VtDictionary) serialization with full type support - ListOp support for all composition types (Token, String, Path, Reference, Payload) - Reference/Payload serialization with LayerOffset and customData - VariantSelectionMap for variant selection metadata - Proper ListOpHeader handling with all operation flags Complex types added: - VtDictionary: uint64_t count + (StringIndex, ValueRep) pairs - TokenListOp, StringListOp, PathListOp: List operations with indices - ReferenceListOp: Full reference composition support - PayloadListOp: Payload composition support - Reference: asset_path + prim_path + LayerOffset + customData - Payload: asset_path + prim_path + LayerOffset - VariantSelectionMap: string-to-string variant selections Implementation details: - All complex types use out-of-line storage (never inlined) - Dictionary values support int32, uint32, float, double, bool, string, token - Reference customData uses MetaVariable::get_value<T>() for type extraction - ListOp uses 8-bit header flags for explicit/added/prepended/appended/deleted/ordered - Proper type detection in PackValue() for all new types Stats: - ~400 lines of serialization code added - 7 major complex types fully supported - All types integrated with PackValue() and TryInlineValue() What can now be written: - USD files with composition arcs (references, payloads) - Variant selections and variant sets - Layer metadata and customData - Full metadata dictionaries - ListOp operations for composition Next: Phase 3 - Animation (TimeSamples, TimeCode) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
