UPDATE: Improved notes and user experience. Let me know what you think.Also I will be tipping Buzz to everyone who upload and tags the model, show me you beautiful work! :)V1.5 720P is out: information on previous version right after.<hr />I've added <a target="_blank" rel="ugc" href="https://github.com/pollockjj/ComfyUI-MultiGPU">ComfyUI-MultiGPU</a>, and it's a game-changer! This advancement allows you to run Hunyuan at resolutions that were previously impossible.

Find the optimal balance for your setup.General info about the workflow and the previous version:Hi everyone, Bizarro here after countless hours of optimization, I’m happy to share the workflow I’ve been using to extract maximum quality and performance from Hunyuan.Credit where it's due, this workflow is based on <a target="_blank" rel="ugc" href="https://www.youtube.com/watch?v=dNc_yu2dEMM&amp;t=331s&amp;ab_channel=AiVerse">This youtuber workflow </a>I’ve been tweaking settings for weeks to get the best quality possible.I’ve also finally solved the issues many had with multiple LoRAs! 🚀 You can mix up to three LoRAs without losing quality and even put several characters in the same scene. It works best with two, but I managed to do three in the example (Bizarro LoRA, Wonder Woman LoRA, and Thanos LoRA).Clarification: I got a bit lucky with the example generation was the first attempt actually I have since discovered it is hard to juggle the LoRAs for consistent results. the Workflow is very fast and the results are pretty great. I will add more examples as I create them. The workflow is great for combining a Lora style with a Lora character as well.You have to work properly with the prompt make sure you describe the characters, for instance "a Caucasian male" clothes, body size etc, where the character is situated in the frame.This workflow is highly optimized for a 3090 and can generate 97 frames at 960x544 in less than eight minutes. If you’re using a card with less RAM, try using a different smaller GGUF version or and reduce quality to 480p.[For more experiments <a target="_blank" rel="ugc" href="https://x.com/AIBizarrothe">follow me on X</a>I ramble all day about video generation and also create<a target="_blank" rel="ugc" href="https://www.youtube.com/@AIBizarroTheater"> funny videos</a>.]This is the GGUF version I’m using, and you can get it here: <a target="_blank" rel="ugc" href="https://huggingface.co/city96/FastHunyuan-gguf/blob/a2c9397340f204cab2a5d0ceca9e3230c570256e/fast-hunyuan-video-t2v-720p-Q5_K_M.gguf">here</a>:<img src="https://image.civitai.com/xG1nkqKTMzGDvpLrqFT7WA/dc36de0a-233d-40ae-a987-afe74068c400/width=525/dc36de0a-233d-40ae-a987-afe74068c400.jpeg" />I tried many LoRA nodes, but they were all really bad. The final breakthrough came when I found <a target="_blank" rel="ugc" href="https://github.com/ronsantash/Comfyui-flexi-lora-loader">this node:</a><img src="https://image.civitai.com/xG1nkqKTMzGDvpLrqFT7WA/9f76e1f6-5a6d-439c-81d5-7a0d8fd8fb0d/width=525/9f76e1f6-5a6d-439c-81d5-7a0d8fd8fb0d.jpeg" />Make sure to set the mode to "In Order." Just select the LoRAs you want and describe each character in detail using the proper trigger words.Multiple LoRA weight values correspond to different steps in the denoising process, controlling how much influence the LoRA has at each stage. Higher weights in early steps shape the overall structure, while later weights refine details. This allows for more nuanced blending, ensuring that a LoRA’s effect isn't applied uniformly but adapts dynamically throughout the image or video generation process.It works really well with two characters, but if you’re patient, you can make it work with three as well.This will work not only for characters but also for all kinds of loras.This works not only for characters but for all kinds of LoRAs.I’d love to see what you come up with!Love,<img src="https://image.civitai.com/xG1nkqKTMzGDvpLrqFT7WA/e9a6d75c-c9ea-4bc6-b140-e638ce2f7aaf/width=525/e9a6d75c-c9ea-4bc6-b140-e638ce2f7aaf.jpeg" /> Mr. Bizarro
