What This Is

Semi-native ComfyUI workflow for Hunyuan Video on low-VRAM hardware. Includes I2V and T2V. Tested on RTX 3050 — works, but slow.

---

Notes

• I2V encodes image into latent space for style — does not animate directly
• T2V works well on low VRAM — check quantisation versions
• Uses GGUF model + upscaler + RifleX
• Low on VRAM? Replace sampler with Tiled KSampler
• Keep all nodes updated — GGUF errors usually fixed by an update
