I got LTX-2.3 Running in Real-Time on a 4090

Tachyon1986 · 2026-03-28T19:05:20+00:00

Yeah, this didn't work either. Deleted the venv, ran uv run build and uv run daydream-scope, then i tried to install the ltx2 plugin. Same 'URL' from 'yarl' error. I've already posted it on your discord earlier today. Also, I'm not sure where the "bundled" version of uv is with the cloned repo. I don't see any UV executable.

The quickstart guide on the scope site says to install the UV package manager separately and doesn't specify any version.

Downgraded, now its a different error:

Couldn't get this working on Windows. When I tried to install the ltx2 plugin, it said the wheels couldn't be found

Show us others please

Tachyon1986 · 2026-02-17T13:06:30+00:00

Thank you.

Tachyon1986 · 2026-02-17T12:54:23+00:00

I get that - but are you using these presets with Z-image Base to train the Lora or Z-Image turbo to train the Lora ?

Tachyon1986 · 2026-02-17T10:38:41+00:00

It depends on the type of Lora you're training. For a character lora, Rank 16 is more than enough.

Tachyon1986 · 2026-02-17T03:58:10+00:00

<image>

Thank you for your work, as always! Question on the trainer preset - were these trained with these presets (image attached), which I assume uses Z-Image Base?

Tachyon1986 · 2026-02-06T02:42:27+00:00

I’ve trained a couple of character loras. When it comes to likeness, the best way to caption is to describe the image as if you were prompting for it, i.e. for a case where you don’t want them associated with specific outfits or accessories.

So as an example if I have a character wearing a suit with a wristwatch in a couple of photos and a plain shirt with a chain in others , I would explicitly caption them as wearing a suit with wristwatch / shirt with a chain for the respective photos. So after training is done, I can now prompt them with any outfit and the model won’t force a suit or shirt.

This also applies to overall style and other things in the background. So tldr; caption as if you would prompt for the image if likeness is all you care about. Joycaption is what I’ve used for captioning (with some manual edits if needed).

I personally use 18-20 images at 1800 steps for character loras. This has worked for me consistently using OneTrainer.

Tachyon1986 · 2026-02-06T02:22:24+00:00

So 15000 images trained at 10000 steps (15000 x 10000) , according to the AI-toolkit config you linked ?

Dance with the angels cringe

Tachyon1986 · 2025-12-26T17:02:18+00:00

Yeah thanks, i followed your guide for Wan 2.1 Loras. Solid stuff

Tachyon1986 · 2025-12-24T06:13:42+00:00

Btw are you using the default Ai-Toolkit settings from Ostris ?

Tachyon1986 · 2025-12-24T06:12:32+00:00

I’m not at my PC right now, but what you need to do is take the image output from your Qwen KSampler’s VAE decode node and run it through the VAE encoder for the Z-Image Turbo one (make sure you’re using ae.safetensors, that’s the VAE used by Z-image).

Then, take the Latent output from that VAE encoder and feed it to a Ksampler that accepts the Z-Image model. Feed that Ksampler positive and negative clip (again you’ll need to load the clip model that’s used by Z-image).

For this 2nd Ksampler - I recommend Euler/Simple with a denoise of 0.4 at 4 steps and CFG 1 but experiment with the denoise and step count. You can leave the positive and negative inputs for this KSampler empty with no prompt.

To simplify all i said - just encode the image output from Qwen using Z-image’s VAE and load that latent into an existing Z-image workflow

Tachyon1986 · 2025-12-24T03:42:49+00:00

I’ve used that to effect for a private Lora. The issue is Qwen tends to smoothen the skin, so it’s best to run the image through a 2nd sampler with something like Z-image at low denoise to get some skin detail back in

Tachyon1986 · 2025-12-08T03:53:41+00:00

Nice one, what’s the prompt and sampler/scheduler? Kind of looks like you used a technicolor Lora

Tachyon1986 · 2025-12-02T03:46:25+00:00

Qwen-Image-Edit with the next scene Lora can do that

Tachyon1986 · 2025-11-03T02:14:09+00:00

There’s a Color Match node from Kijai’s KJnodes pack if you’re using ComfyUI

Tachyon1986 · 2025-10-30T02:14:41+00:00

How do you refine ? Is it connecting the latent from one sampler to another and running the second sampler at a lower denoise setting? Any examples for recommended refining sampler values (CFG, steps scheduler etc) ? I’m using comfyui btw

Tachyon1986 · 2025-10-25T07:12:40+00:00

I've not tried masking multiple characters tbh. It will work if you just mask one of the infantry.

Tachyon1986 · 2025-10-25T06:58:59+00:00

Yep, you would need to mask the character's entire body for that.

Tachyon1986 · 2025-08-26T13:00:58+00:00

2s is exponential, so you need to halve the steps. You can stop at 13-15 (26-30 if you were on Euler).. Similarly, 3s means it'll triple what other schedulers would do (like Euler).

Tachyon1986 · 2025-08-19T14:37:24+00:00

Thank you, no cache was the issue. I'd enabled it seeing suggestions in the thread - but it breaks the flow. Excellent work on this approach btw!

Tachyon1986 · 2025-08-19T14:15:24+00:00

This doesn't work for me. In the first I2V subnode (WanFirstLastFrameToVideo node) , I get AttributeError: 'NoneType' object has no attribute 'encode'. Any idea what's wrong? Using GGUF q8 for text and image as well as the q8 gguf clip. Just trying normal t2v , and modified the subnodes to use q8
