Node graph blueprint: SD 3.5 Large × ControlNet Depth & Pose Lock
This route pairs **SD 3.5 Large** with a **ControlNet Depth & Pose Lock** setup designed for locking camera composition and human pose from a reference frame. Place your model weights in `models/checkpoints/` and start the graph with **Load Checkpoint + TripleCLIPLoader**.
Core wiring chain: `DepthAnything / DWPose Preprocessor → Apply ControlNet (Advanced) → KSampler`. Connect your positive and negative conditioning from CLIP Text Encode into KSampler and decode to RGB pixels.
VRAM tuning and execution tips on Windows
- **Memory target (12 GB+):** If your GPU sits at 8 GB or 12 GB, use FP8 or GGUF Q4/Q5 weights and swap in VAE Decode (Tiled) to avoid end-of-pass memory spikes.
- **Workflow persistence:** Every image saved by this route embeds the full JSON graph inside the PNG metadata — drag the output back onto ComfyUI Studio anytime to resume.
- **Get the app:** Download the Windows desktop or portable build from /download.
FAQs
Which loader node do I use for SD 3.5 Large in a ControlNet Depth & Pose Lock?
Use `Load Checkpoint + TripleCLIPLoader` with weights stored in `models/checkpoints/`, then wire the output into `DepthAnything / DWPose Preprocessor → Apply ControlNet (Advanced) → KSampler`.
How much VRAM does SD 3.5 Large need for ControlNet Depth & Pose Lock?
Target VRAM is 12 GB+. On 8 GB cards, load quantized FP8 or GGUF weights and enable tiled VAE decoding.
