For better controllability, workflows using Wan2.2 TI2V-5B for image-to-video or Wan2.2 Animate for character animation are recommended, while VACE-Fun-style workflows provide precise motion and structure control for LEGO-like subjects.", "body_md": "Hmm… it is hard to give specific advice without knowing your budget, GPU/VRAM situation, or preferred software, but broadly speaking, I would think about it like this:\n\nThere probably is not one single “correct” model for LEGO video.\n\nI would choose by **workflow**, not only by model name.\n\nA useful way to split the problem is:\n\nA LEGO LoRA can help with the first part, but it does not automatically solve all the others. For video, the workflow matters a lot.\n\nVery short version:\n\n`Remade-AI/Lego`\n\n`Wan2.1 14B T2V`\n\n`Wan2.2 TI2V-5B`\n\n`LTX-Video`\n\n`HunyuanVideo 1.5`\n\n| Route | Best when | Input needed | Ease | GPU / cost | Why it fits LEGO video | Main caveat |\n|---|---|---|---|---|---|---|\n`Remade-AI/Lego` |\n\n`Wan2.1 14B T2V`\n\n`Wan2.2 TI2V-5B`\n\n`LTX-Video`\n\n`HunyuanVideo 1.5`\n\n`Remade-AI/Lego`\n\n+ `Wan2.1 14B T2V`\n\nIf someone asks literally “which model can produce LEGO-style video?”, the most direct open asset I found is:\n\nIt is a LEGO-style LoRA for [ Wan2.1 14B T2V](https://huggingface.co/Wan-AI/Wan2.1-T2V-14B). The model card includes useful practical details:\n\n`lego_35_epochs.safetensors`\n\n`wan_txt2vid_lora_workflow.json`\n\n`l3g0_5ty13 Lego animation style`\n\nThis makes it the cleanest direct answer.\n\nHowever, I would be careful about what it is and is not.\n\nIt is not a small standalone LEGO video model. It is a LoRA on top of a heavy Wan2.1 14B T2V base. It helps the model produce a LEGO-like style, but it does not automatically solve:\n\nSo I would use this when the main goal is:\n\n“Give me a direct LEGO-style T2V option.”\n\nI would not assume it is automatically the cheapest or most controllable route.\n\nBest label:\n\nMost direct LEGO-specific route.\n\nIf the user can make or provide a good LEGO-style still image, I would probably recommend this as the practical default:\n\nLEGO-style keyframe/reference image →\n\n[or another Wan2.2 I2V workflow.]`Wan2.2 TI2V-5B`\n\nThis is less “one model magic” and more “good production logic.”\n\nThe reason is that LEGO video is both a **style problem** and a **structure problem**.\n\nA text prompt such as “LEGO animation” may not reliably preserve:\n\nA strong keyframe/reference image gives the video model something concrete to preserve.\n\nSo the workflow becomes:\n\nThis can be more controllable than pure T2V, even though it adds one preparation step.\n\n[ Wan2.2 TI2V-5B](https://huggingface.co/Wan-AI/Wan2.2-TI2V-5B) is especially relevant because it supports both text-to-video and image-to-video. The\n\nCost note: I would call this **workflow-dependent**, not simply “cheap.” Resolution, frames, offloading, quantization, FP8/GGUF variants, and the exact ComfyUI workflow can change the real VRAM picture.\n\nBest label:\n\nMost practical modern open route.\n\nIf the goal is a LEGO minifigure, toy character, or a recurring LEGO-like character, [Wan2.2 Animate](https://docs.comfy.org/tutorials/video/wan/wan2-2-animate) is very important.\n\nThis is not just ordinary text-to-video.\n\nIt is closer to:\n\n“Here is the character. Make it move like this video.”\n\nThat is often much closer to what people mean by “animation.”\n\nThe Wan2.2 Animate guide describes two modes:\n\nFor LEGO/minifigure use, the difference matters.\n\nUse **Move-like logic** if you want:\n\nUse **Mix/replacement-like logic** if you want:\n\nThis route is stronger than pure T2V for character animation, because it uses an actual reference image and motion source.\n\nBut it has requirements:\n\nBest label:\n\nBest LEGO/minifigure character route.\n\nIf the user needs precise motion/structure control, I would move beyond style LoRA and into control workflows.\n\nThis is the route for cases like:\n\nWan2.2 Fun Control / VACE-Fun-style workflows are relevant because they can use control conditions such as:\n\nThis is closer to a production/control workflow than a simple “style model” workflow.\n\nFor LEGO animation, this can matter a lot. LEGO-like subjects have strong structure: blocks, joints, flat surfaces, toy proportions, and visible edges. If the output keeps morphing or drifting, a style LoRA alone may not be the right tool. A control-heavy workflow can give the model more constraints.\n\nHowever, this is also the route most likely to become expensive and technical.\n\nThe tradeoffs:\n\nI would not start here unless the user specifically needs control.\n\nBest label:\n\nBest control-heavy route; ideal when needed, overkill otherwise.\n\n[ LTX-Video](https://github.com/Lightricks/LTX-Video) /\n\nIt is not LEGO-specific, but it fits the same practical strategy:\n\nmake LEGO-style keyframes first, then animate/extend them.\n\nLTX-Video is relevant because the project describes support for:\n\nThat makes it useful if the user wants to think in keyframes or shots instead of one long prompt.\n\nFor example:\n\nThis is not as direct as a LEGO-specific LoRA, but it may be more useful for a real animation workflow if the user can provide strong keyframes.\n\nBest label:\n\nGood modern non-Wan I2V/keyframe route.\n\n[ HunyuanVideo 1.5](https://github.com/Tencent-Hunyuan/HunyuanVideo-1.5) is another modern open-video base worth knowing about.\n\nI would not make it the main LEGO-specific recommendation, because the LEGO/reference-control story here is more directly supported by the Wan and LTX workflows above.\n\nBut if the user is broadly comparing current open T2V/I2V video bases, HunyuanVideo 1.5 belongs in the list. It is a modern 8.3B open-video model family with T2V/I2V positioning and consumer-GPU-oriented messaging.\n\nFor this specific question, I would mention it as:\n\nanother modern general open-video base, not a LEGO-specific route.\n\nBest label:\n\nAdditional modern general video base.\n\nOlder Stable Diffusion / AnimateDiff / SVD-style workflows still have a place.\n\nThey can be useful if:\n\nA fallback workflow might look like:\n\nThat said, if the user is asking now about “a model for LEGO video,” I would not make this the first recommendation unless they are clearly VRAM-limited.\n\nBest label:\n\nUseful fallback, not the first modern recommendation.\n\n| Trap | Why it matters | Safer approach |\n|---|---|---|\n| Looking for one magic “LEGO video model” | LEGO style, subject identity, motion, and structure control are separate problems. | Choose by workflow: direct T2V, keyframe→I2V, character animation, or control-heavy. |\n| Starting with pure T2V only | It looks simple, but it can be hard to preserve LEGO look, framing, subject identity, and motion. | Make a LEGO-style keyframe/reference image first, then animate it. |\n| Treating LoRA as plug-and-play | A LoRA usually depends on the correct base model, trigger phrase, strength, and workflow. | Read the model card and start from the provided workflow when available. |\n| Using a style LoRA to solve a motion problem | LoRA can help appearance, but it does not automatically solve pose, camera movement, trajectory, or temporal consistency. | Use I2V, Animate, or control-video workflows when motion/control matters. |\n| Confusing Wan2.2 Animate modes | Move and Mix/replacement target different workflows. | Decide whether you want to animate a reference character or replace a character in an existing video. |\n| Treating control workflows as cheap | Fun/VACE-style workflows can be powerful but heavy; control weights and workflows can be large. | Use them only when you actually need pose/depth/Canny/MLSD/trajectory/camera control. |\n| Ignoring non-Wan I2V options | Wan is a strong default, but LTX has useful I2V/multi-keyframe/keyframe workflows. | Keep LTX as a modern alternative if the project is keyframe-driven. |\n| Confusing “easy setup” with “easy result” | A text-only workflow may be easy to launch but hard to steer. | Keyframe→I2V is often easier in result-space even if it adds one step. |\n| Underestimating GPU cost | Video generation is much heavier than ordinary image generation. | Test short clips first, then scale resolution, frames, and model size. |\n| Trying to make one long clip immediately | Long clips amplify drift, identity loss, and motion errors. | Generate short shots, then stitch the best ones. |\n\nIf I had to turn the above into practical advice, I would choose like this:\n\nTry:\n\n[ Remade-AI/Lego](https://huggingface.co/Remade-AI/Lego) +\n\n`Wan2.1 14B T2V`\n\nThis is the cleanest direct model/link answer.\n\nTry:\n\nLEGO-style keyframe/reference image → [ Wan2.2 TI2V-5B](https://huggingface.co/Wan-AI/Wan2.2-TI2V-5B) / Wan2.2 I2V\n\nThis is probably where I would start if the user has unknown hardware and wants something current.\n\nTry:\n\nLEGO character reference image + driving/performer video → [Wan2.2 Animate](https://docs.comfy.org/tutorials/video/wan/wan2-2-animate)\n\nThis is much closer to “animate this character” than pure text-to-video.\n\nTry:\n\nWan2.2 Fun Control / VACE-Fun-style workflows.\n\nThis is for pose, depth, Canny, MLSD, trajectory, camera, and control-video use cases. It is powerful but heavy.\n\nTry:\n\nEspecially if you want I2V, multi-keyframe, keyframe-based animation, or video extension.\n\nUse a fallback:\n\nSDXL/FLUX LEGO-style image generation → older/lighter I2V or AnimateDiff/SVD-style workflow.\n\nThis may be less modern, but it may be more realistic on weaker hardware.\n\nThe ideal route would probably not be one model.\n\nIt would be a pipeline:\n\nIn model/workflow terms, that might mean:\n\n`Wan2.2 TI2V-5B`\n\n`LTX-Video`\n\nThe control signals might include:\n\nThis is probably the most controllable route.\n\nIt is also the most workflow-heavy and GPU-expensive route.\n\nFor video generation, “easy” does not only mean easy installation.\n\nIt also means easy to get the intended result.\n\nPure text-to-video may look easiest because you only type a prompt. But it can be difficult to steer. A keyframe→I2V workflow has one extra step, but it often gives the model a stronger visual anchor.\n\nLikewise, “cost” mostly means GPU/VRAM cost.\n\nThe actual cost depends on:\n\nSo I would test in this order:\n\nIf you are new to LoRAs/video workflows, I would start from an existing workflow rather than wiring everything manually.\n\nFor these routes, [ComfyUI](https://github.com/Comfy-Org/ComfyUI) is probably the safest first place to look, because many Wan/LTX workflows are shared as ComfyUI workflows or templates.\n\n[Forge Neo / sd-webui-forge-classic](https://github.com/Haoming02/sd-webui-forge-classic) may also be worth checking if you prefer a WebUI-style interface, and it mentions Wan 2.2 support. But for current video-control workflows, I would still treat ComfyUI as the safer first path.\n\n| Purpose | Link |\n|---|---|\n| Direct LEGO video LoRA |\n`Remade-AI/Lego` |\n\n`Wan-AI/Wan2.1-T2V-14B`\n\n`Wan-AI/Wan2.2-TI2V-5B`\n\n`Wan2.2-VACE-Fun-A14B`\n\n`LTX-Video`\n\n`HunyuanVideo 1.5`", "url": "https://wpnews.pro/news/a-model-for-lego-production", "canonical_source": "https://discuss.huggingface.co/t/a-model-for-lego-production/176779#post_2", "published_at": "2026-06-15 00:09:27+00:00", "updated_at": "2026-06-15 00:17:36.839878+00:00", "lang": "en", "topics": ["generative-ai", "large-language-models", "computer-vision", "ai-tools", "ai-research"], "entities": ["Remade-AI", "Wan-AI", "Wan2.1 14B T2V", "Wan2.2 TI2V-5B", "Wan2.2 Animate", "Hugging Face", "ComfyUI", "VACE-Fun"], "alternates": {"html": "https://wpnews.pro/news/a-model-for-lego-production", "markdown": "https://wpnews.pro/news/a-model-for-lego-production.md", "text": "https://wpnews.pro/news/a-model-for-lego-production.txt", "jsonld": "https://wpnews.pro/news/a-model-for-lego-production.jsonld"}}
