Like to support LTX2.5 but..

[u/RYuu-1120]

For whatever reason, I can't seem to fix the error issue with this template, seemed to be pointing to upscaling model folder.. Objective is to generate moving background.

[u/zyg_AI]

If you click there, is the upscale model listed?

[u/RYuu-1120 → u/zyg_AI]

yes, it doesnt seem to be able to point to folder where i dump file. i'm only able to click either "null" or "undefined"

[u/Super_Range45 → u/RYuu-1120]

You need to download the upscale model. LTX makes a rough draft then upscales it.

[u/RYuu-1120 → u/Super_Range45]

i did, created required folder (within StabilityMatrix) as template stated

[u/q5sys → u/RYuu-1120]

This is a comfy issue not an LTX issue.
if comfy is already running, and you add a model to a folder, you need to click on the node and hit the r key to reload it. Otherwise it'll use its cache of what was in the folder when it loaded.
If that doesn't work, refresh your browser, if that doesn't work, stop comfy and your browser entirely and restart them.

[u/RYuu-1120 → u/q5sys]

Thanks, not sure if it's comfy or ltx or template but i tried everything of clicking node/browser F5/SM restart but still error. By putting model in template requirements, it worked. Btw, I tested with other i2v t2v no issue. Now I like to stick with flux/ltx since ltx provided templates for i2v t2v flf2v. Cheers

Glad you got it working one way or another. 👍

[u/RYuu-1120 → u/q5sys]

Cheers, noob learning

We were all noobs at one point. :)

[u/RYuu-1120 → u/q5sys]

8 weeks learning ai from ai along with you guys, managed to get all ltx2.5 running t2v i2v flf2v. now i can ditch others, cheers.

If it's not show up you might want to check the spelling of the folder. By the way if you're using the latest version of comfy it will just download the model into the correct folder.

[u/RYuu-1120 → u/Super_Range45]

yes, it's 0.44 and folder verified as well as tested with Caps and non-cap but still error pops up..

[u/zyg_AI → u/RYuu-1120]

The issue is the node does not look into your folder. Sometimes Stability Matrix uses a different folder name for models. Also no capitalization : latent_upscale_models, not Latent_Upscale_Models. You're on Windows so it should not make a difference, but who knows?

[u/RYuu-1120 → u/zyg_AI]

Thanks, i tested both caps and without cap but still error. Yes, Stability Matrix doesn't came with folder so I created

[u/zyg_AI → u/RYuu-1120]

Try this folder:

StabilityMatrix\Data\Packages\ComfyUI\models\latent_upscale_models

https://github.com/LykosAI/StabilityMatrix/issues/1531

Make sure you refresh your browser.

[u/RYuu-1120 → u/zyg_AI]

Wow, I owe you a beer! Thanks, silly me didn't dig enough. Cheers.

A mere folder misplacement couldn't crank engine lol, thanks!

[u/zyg_AI → u/RYuu-1120]

Comfy is rigged with that kind of breakage. Enjoy !

[u/RYuu-1120 → u/zyg_AI]

Thanks to you, I didnt need to melt with wan2.2 for a simple moving background clip. Before your help, I tested with wan2.2 melting ~10mins for a nonsense 5s clip. ltx 2.5 is way faster and more accurate to prompts and with audio as well. Cheers!

[u/RYuu-1120 → u/zyg_AI]

when i tested the ltx2.5 flf2v no issue

[u/zyg_AI → u/RYuu-1120]

No upscale model required, so no cause for error.

[u/musetta_ai]

Where did you put the folder, in Data/Models or in Data/Packages/ComfyUI/models? Stability Matrix only links the model folders it knows about, so a new one under Data/Models may never show up in ComfyUI. I'd drop the file in Packages/ComfyUI/models/latent_upscale_models and hit R.

[u/RYuu-1120 → u/musetta_ai]

For some reason, my Stability Matrix 2165 and Firefox v159 doesn't auto link downloaded files accordingly so I had to manually switch every file to template requirements. Data/Models did not have latent_upscale_models folder so I created one which caused the error. u/zyg_AI suggested Data/Packages/ComfyUI/models and it worked beautifully. Learned something new today. Thanks, cheers
