Node graph blueprint: Hunyuan Video × Text-to-Image Graph
This route pairs **Hunyuan Video** with a **Text-to-Image Graph** setup designed for clean base generation from positive and negative prompts. Place your model weights in `models/diffusion_models/` and start the graph with **UnetLoaderGGUF / Load Diffusion Model**.
Core wiring chain: `EmptyLatentImage → KSampler → VAE Decode → Save Image`. 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–24 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 Hunyuan Video in a Text-to-Image Graph?
Use `UnetLoaderGGUF / Load Diffusion Model` with weights stored in `models/diffusion_models/`, then wire the output into `EmptyLatentImage → KSampler → VAE Decode → Save Image`.
How much VRAM does Hunyuan Video need for Text-to-Image Graph?
Target VRAM is 12 GB–24 GB. On 8 GB cards, load quantized FP8 or GGUF weights and enable tiled VAE decoding.
