- Implemented WanVideoVACEEncode class for encoding with VACE, including input parameters for width, height, number of frames, and strength.
- Enhanced WanVideoEncode class to support multi-GPU encoding, with additional parameters for noise augmentation and latent strength.
- Updated device management to ensure proper device context during encoding processes.
Advanced Checkpoint Loaders allow users to map each of the elements of the checkpoint to a different device, or in the case of DisTorch2, shard the UNet and CLiP .safetensors arbitrarily whilst ensuring actual computation remains on selected `compute` device.
Added example workflow for standard and DisTorch2 MultGPU checkpoint loaders.
This commit introduces a major reorganization of the `examples` directory to improve clarity and discoverability. Workflows are now grouped into subdirectories based on the features they demonstrate (e.g., `distorch`, `distorch2`, `gguf`, `multiGPU`).
Key changes:
- Moved existing example JSON files into new categorized folders.
- Added several new and updated workflows, particularly for DisTorch2.
- Removed outdated or redundant example files.
- Renamed an internal function from `..._gguf_v2` to `..._safetensor_v2` to better reflect its broader functionality in DisTorch2.
- Created custom implementations for all WanVideo nodes with explicit device selection
- Added WanVideoBlockSwap with dual device control (swap_device and model_offload_device)
- Created WanVideoModelLoader_TWO for multi-model workflows to avoid race conditions
- Discovered core ComfyUI bug: safetensors loader ignores device index (uses device.type instead of str(device))
- All wrapper nodes use runtime module patching to override WanVideoWrapper's cached device variables
- Extensive logging added for debugging device assignments
