Model hash name changed and images are totally different after the update

[nemesiscompletion]

I think it's update from this year...the images I create are not the same anymore

Just in case, I kept the old version and updated version on separate folder
I loaded exactly same pic on PNG info, sent into txt2img to generate it again

As you can see here, the images are not the same at all
The more complicated the prompts are, I see there's greater difference in the pics

The settings (ENSD, Sigmas, etc.) are exactly the same
Xformers are disabled on both version

What I also realized is even though they are exactly the same model, the model hash appears differently from new version for some reason
It's not just this model, but every single models are having different model hash even though they are the same models

What should I do in order to get the images look the same?
I find the order version has less problem (less fused limbs) and the quality is also better, but older version do not support some of the features I need to use (like LoRA and controlnet)
I'd like to be able to create same images on update version but I'm clueless what to do here
Does anyone know solution for this?

Perhaps it's kinda like on civitai - where there's 3-4 calculated hashes per model available -> perhaps your model is still right, but one of the other calculated hashes is shown?

This will not help with the hash-values/names, but take a look to Settings/Compatibility. I could restore a lot of old behavior with "Use old karras scheduler sigmas (0.1 to 10)."

I've tried everything 1 by 1 in the Compatibility tab, but they are not getting result anywhere similar to the original image
Also, I noticed that if I change between models and go back to them or refresh them, sometimes image changes completely or slightly different even if they are made by same models

Hello would you add me on discord ?
discord : mythic4530
I would like to talk with you about this.
In case you don't wanna add me or do not use discord at all, The question was about ; if you still have the old files can you share it with me ? I would like to generate with old engine too. I have the same issue as you but I only have updated version..

The hash algorithm changed about a year ago, but that won't affect generation at all.

Are your resolution/hires fix settings different? In your first screenshot it looks like you're generating at 512x704 (normal enough), but in the second you're generating at 448x640 and then doing a hires fix upscale to 512x704. It looks like you might have set the hires fix resolution when you meant to set the base res. Try turning hires fix off entirely and comparing non-upscaled generation.
