MiniMax H3 Speedup Test: Turbo LoRA vs. Kitchen Attention

MiniMax H3 is great, but it’s a total compute hog.

I tested two ways to speed it up—Turbo LoRA (reducing step counts) and Kitchen Attention (faster per-step backend)—using the exact same prompt, seed, and resolution.

Video review here

Edit: Here’s the workflow, if you want to test it out - https://drive.google.com/file/d/1425fNNR_C9ErIiutR_FBhtQlOKzJ_Tfh/view?usp=sharing

The Breakdown:

• Turbo LoRA: Cuts steps, but quality tanks. At 8 steps it gets soft and drifts; by 4 steps it's completely broken with heavy face artifacts.

• Kitchen Attention: Keeps all 20 steps, but chops ~30% off the render time with zero quality loss. Just update ComfyUI and set it in the attention backend node.

• LoRA + Kitchen Attention: The backend isn't causing the artifacts—the LoRA is.

audio stays decent at low steps even while the visuals fall apart.

Verdict: Skip the Turbo LoRA for now. Kitchen Attention is basically a free 30% speed boost, so just leave that on.

Looking for high-end Product Photography workflow advice: 3D Renders + Texture Ingestion + Custom Studio Lighting (Intern wanting to blow my boss away!)

Hey everyone,

I’m currently doing my internship and working on setting up an AI-assisted product photography pipeline for high-end furniture. I really want to deliver the best of the best and blow my boss away with what ComfyUI can do, so I’m reaching out to see if anyone has a battle-tested workflow or advice for this specific setup.

Here is the exact pipeline I’m aiming to build:

  1. Exact Geometry Retention: Starting with 4 Blender renders/passes of the furniture piece so the 3D form, proportions, and edges are 100% accurate (ControlNet Depth + Canny/Lineart).
  2. Multi-Texture Ingestion via Image Reference: Injecting real photo references for specific materials (e.g., a specific high-res wood grain for the body, leather texture for details/handles). I assume masked IP-Adapter or regional conditioning is the way to go here?
  3. Custom Studio Setting & Lighting: Placing it in a minimalist neutral grey studio setting, but with our own signature dramatic light and shadow style (considering IC-Light, specific ControlNets, or Style LoRAs).
  4. Ultra-High-Res Output: Multi-pass rendering / ultimate upscaler to get crisp micro-textures without plastic AI artifacts.

My questions for the experts here:

  • Does anyone have a .json workflow template or a similar node architecture they’d be willing to share as a starting point?
  • What’s the current gold standard stack for this? (Flux vs. SDXL for texture fidelity + IC-Light vs. regional IP-Adapter?)
  • Any crucial custom nodes / techniques I shouldn’t overlook for keeping industrial product accuracy intact?

Any workflow links, node suggestions, or tips would be massively appreciated. Thank you in advance for helping me out!

[Custom Node] MiniMax H3 FlowDirector – Better motion & generation flow control for MiniMax H3 (Example Workflow included)

Hey all,

I built MiniMax H3 FlowDirector to streamline MiniMax H3 workflows and provide cleaner control over video generation flow without spaghetti wiring.

 Cleaner Pipelines: Replaces complex routing with a single, dedicated node.

 Better Motion Flow: Helps guide generation parameters more consistently.

 Plug & Play: Slots directly into your current H3 setups.

Example Workflow:

A drag-and-drop ⁠.json⁠ workflow is included in the repository so you can test it immediately.

Links:

 GitHub: https://github.com/AlonAshken/ComfyUI-MiniMaxH3-FlowDirector

 Comfy Registry: https://registry.comfy.org/publishers/vorpalblade/nodes/comfyui-minimaxh3-flowdirector

 ComfyUI-Manager: Search for ⁠FlowDirector⁠ or ⁠MiniMaxH3-FlowDirector⁠.

I did this after needing that option because I don’t have a ton of vram and customized a node that was first created by aitrepreneur (he’s awesome check his YouTube videos and stuff)

what I created works well for me but might not be perfect feel free to fork and change it however you want

ComfyUI Tutorial MiniMax H3 4 Steps Lora + Upscaling + 2X Faster Generation! Best Settings for 2K AI

Hello everyone

Want to get faster MiniMax H3 video generation without sacrificing quality? In this tutorial, I’m testing the new H3 LoRA together with Sage Attention, Sol Attention, and Spectrum nodes to find the best combination for speed and quality. The goal is to push MiniMax H3 as far as possible while cutting generation times by up to , then upscale the results with LTX Upscaler to reach a stunning 2432 × 1344 (2K-class) resolution. By combining both H3 LoRA together with Sage Attention, Sol Attention, and Spectrum nodes I generated video at 0.8 megapixel using "**RTX3060 6GB 16GB RAM "**and I got

 13 minutes vs 41 minutes at 8 steps

 27 minutes vs 52 minutes at 20 steps

LTX 2.3 Upscaler 11 minutes to get 2432 × 1344 resolution

Just a PSA

What I’m getting at is that, now that vibe coding is a thing, everyone is creating custom nodes left and right. The problem is that people are making their own MiniMax director nodes, image-editing nodes, and countless others without first checking whether something similar already exists.

Instead of branching off in dozens of different directions, we could come together and help improve the nodes that are already available. A lot of custom nodes are also essentially standalone apps running inside ComfyUI, designed for only one specific purpose. Whenever possible, nodes should remain flexible and modular so they can be integrated into different workflows and potentially help people create something new and interesting.

There have also apparently been people hiding malware inside custom nodes. Encouraging users to research existing nodes before downloading or creating another one could reduce unnecessary duplication while also helping keep the ComfyUI community safer.

I moved client delivery off ComfyUI. I still use it for everything else.

ComfyUI is still the better tool when I’m exploring a look, testing ControlNets, dialing in an IPAdapter workflow, or building something I’ll reuse. But client work is different. Last week, a client changed the art direction at 11pm: same product, but four new compositions, a different background palette, and usable files by 9am.

My Comfy workflow was tuned for the original brief, specific LoRAs, masks, ControlNet settings, upscaling pass, and output logic. Changing the concept meant touching half the graph and rechecking every stage. It was powerful, but it wasn’t fast.

So now I use ComfyUI for R&D and repeatable production pipelines. For last-minute client variants, I use hosted tools where I can generate, iterate, and hand off without rebuilding the machine underneath it.

Anyone else split their workflow this way, or am I committing heresy?

Noisy outputs in Krea 2 in ComfyUI

I have a problem. Recently my outputs in Krea 2 have blotches/banding/noise. This occurs on smooth surfaces and the edges of objects.

Images without reddit compression: img1, img2, img3

Things I tried today, but that didn't make any difference:

  • Krea2 turbo int8 convrot / fp8 / bf16 / raw fp8
  • Windows ComfyUI 0.31 / 0.30 / 0.26
  • comfy-kitchen 0.2.30 / 0.2.27 / 0.2.10
  • PyTorch 2.12 cu132 / 2.12 cu130 / 2.8 cu128
  • Older NVIDIA driver

anyone else experienced this? any ideas?

Tiled upscaler for FLUX.2 klein (and similar models)

Explanation after the images.

Before

After

Before

Before

After

FLUX.2 [klein] (and reference-latent edit models in general) have a resolution limit per call. If you want to add real detail to something (sharpen fabric texture, hair, stitching) you can do it working with it in pieces. The obvious way to do that turned out to be full of dead ends, so here's what I learned.

What it does: splits the image into overlapping tiles, regenerates each one at the model's native resolution, and blends them back into one image.

My first attempt did tiling the"proper" way: the MultiDiffusion/Mixture-of-Diffusers trick, where you slice the latent and blend the per-step noise predictions. That works great on convolutional UNets (SD1.5/SDXL), because a convolution is local, it doesn't care where in the canvas a patch sits.

FLUX is a transformer with absolute position embeddings (RoPE), not a UNet. Hand it a raw slice of a bigger latent and it has no idea it's a fragment, it just sees "a small complete image" and redraws the entire subject inside every tile. Every tile becomes a full (wrong-scale) copy of the whole scene.

I found that FLUX's RoPE positions can be shifted per-call via transformer_options so I tried telling each tile where it really sits in the canvas. Didn't help. Turns out FLUX applies that same shift to the tile and to any attached reference latent, so the relative offset between them (the only thing that matters for attention) never changes. Patching the model's forward pass to shift only the tile and not the reference removed the duplication, but the model still composed each slice as a standalone image, it was never trained to generate fragments, so proportions came out wrong regardless.

What actually worked: don't fight the model's training. Tile in pixel space. Every call is a complete image at a resolution it knows how to handle and solve everything else (continuity, color, blending) outside the model:

  - each tile is cropped from the canvas of already-generated neighbours, so it continues real pixels instead of guessing that region blind

  - per-tile color matching back to the source, so tiles don't drift in exposure/tint

  - blend weights derived from the actual per-side overlap, not the requested one (if the fade is narrower than what two tiles really share, you get a flat 50/50 band in the middle.

One node, no manual ReferenceLatent/EmptyLatent/KSampler wiring. You just give it a model, plain CLIPTextEncode conditioning, a VAE and an image.

GitHub: https://github.com/GianlucaMancuso/ComfyUI-TiledUpscale

Also on the ComfyUI Registry, search "TiledUpscale" in Manager.

Happy to answer questions, and if anyone knows a cleaner way to condition a transformer edit model on true image fragments, I'd genuinely like to hear it.

Looking for a High-Quality AI Face Swap & Character Replacement Workflow

Hello everyone,

I’m looking for a high-quality workflow that can replace the character/face in an existing video with my AI model while keeping the original video as identical as possible.

My main goal is to preserve the original body, movements, expressions, pose, camera motion, background, lighting, composition, and overall video quality, while changing only the character’s identity/face.

I’m specifically looking for a professional workflow that can produce highly realistic results with strong identity consistency, natural skin texture, accurate facial details, and minimal artifacts or quality loss.

Ideally, the final output should look like the original footage was actually recorded with the AI model rather than appearing like an obvious face swap.

If anyone has a reliable ComfyUI workflow, custom setup, or a paid workflow/course that can achieve this level of quality, please feel free to contact me.

[Node] Auto-save your workflow as JSON every run — never lose track of which settings actually worked

Body:

Made this because I kept losing track of which parameter tweaks actually gave me the good result. You know the drill — nudging the sampler, swapping a LoRA weight, tweaking the prompt fifteen times, and then twenty minutes later going "wait, which one of these was the good one again?"

So I built a node that just saves your whole workflow as a JSON file every single time you hit queue. No setup, no remembering to hit "save" manually — you drop it in your graph once and it quietly keeps a snapshot of every run in the background.

A few things it does that I found genuinely useful once I started using it daily:

- If you point it at your SaveImage or VideoHelperSuite output, it names the JSON after your actual output file, so the workflow and the render sit right next to each other with matching names
- You can dump them into date folders automatically if you don't want one giant flat pile
- It never overwrites — if two runs would collide it just appends _1, _2, etc.
- You can also tag variants with a postfix if you're A/B testing something (like _seedA / _seedB)

Honestly wasn't planning on publishing this, it started as a personal utility, but figured other people probably run into the same "which run was the good one" problem so might as well share it.

Install:
comfy node install comfyui-export-workflow-node

or just search "Export Workflow Node" in ComfyUI Manager.

Repo's here if you want to poke at the code or file an issue: https://github.com/kotakcloud/ComfyUI-Export-Workflow-Node

Let me know if it breaks on your setup or if there's a filename pattern you wish it supported, happy to add stuff.
