[Question]: Multidiffusion-upscaler-for-automatic1111 integrated or not?

[Vigilence]

Is there an existing issue for this?

• I have searched the existing issues and checked the recent builds/commits

What would your feature do ?

I know the project page says multidiffusion-upscaler-for-automatic1111 is integrated into forge but I don't see any of the functions that are similar to the original multidiffusion project, included Tiled Vae, Tiled Diffusion (with upscale), Tiled Noise Inversion, and Regional Prompt Control.

Could it be that the extension mentioned for removal is wrong?

• Here is what we are told to remove since its integrated - https://github.com/pkuliyi2015/multidiffusion-upscaler-for-automatic1111

• Here is what seems to actually be integrated - https://github.com/tfernd/HyperTile

About Extensions
ControlNet and TiledVAE are integrated, and you should uninstall these two extensions:

sd-webui-controlnet
multidiffusion-upscaler-for-automatic1111

this is the only reason I'm not fuly switching to forge now. the tiled vae does work but its many times slower than the TiledVae option in Multidiffusion-upscaler extension

I have heard some similar reports about the integrated Tiled VAE not as good/fast as the old Tiled VAE,

but no one ever shown an example and it is very difficult for us to judge.

I tested a lot of images and i never see difference.

Help wanted if someone can give some examples that I can reproduce and look at

Hello!

The issue this post brings up is that the page for this project indicates that tiled diffusion is integrated into forge, if it’s not then the instructions should be corrected so people know that tiled diffusion isn’t integrated.

What is actually integrated is hypertile which is something else.

Hi please note that Tiled VAE is integrated and enabled automatically when image is too large for your GPU, and, the native diffusion resolution from Forge without using tiled diffusion is bigger than what i used to often use with standard webui + tiled diffusion.

In theory tiled diffusion can support infinite resolution, but when people go to like 16k, they are using low denoising strength and in that case Ultimate SD Upscale is much better not only in live preview user experience but also for several avaliable options like how to fix seams

But tiled diffusion has several other functionalities like noise inversion, regional XXX, etc. But those functionalities are not updated for half a year and I am not sure do they even work in original webui 1.7.0. If they do not, then we can ignore them, but if they do, then we can add somethings to to-do (but for god sake do they really still works now?

I added help wanted and see if anyone want to maintain a new extension for tiled diffusion. With forge that should need about 200 lines of codes

Multi-Diffusion is also intergrated now, feel free to open other issues if they have some problems

@lllyasviel Thank you for clarifying! Tiled Diffusion works exceptionally well for me once I figured out the issue it was having, which is that the scale factor must match "resize by" or "resize to" size. I manage to go to 16k with increase in detail and no visible seems with little effort on my part.

So currently since tiled vae and multi diffusion is integrated, but does not have the upscale function of the original extension, what would we do for the upscaler? In other words, how would upscale using the integrated tiled diffusion if the upscale model is no longer selectable?

If its not too much trouble can you add some info on what the HyperTile Integrated tab does and how to use it, or point me to the original extension page that has that info?

Thank you.

I am trying but so far it only generate different tiles. So what are the requirement to get it to works as intended? As far as I know the other feature still work as intended on A1111. I use region control and noise inversion relatively often.

There an examples of the tiles not working properly in Forge.

There an example of the region control made in A1111 1.7. This feature is still working as expected and it is really useful to make specific image composition or to include multiple character in scene.

3 weeks and no answer? Please @lllyasviel enlighten us how to use tiling to resize an image ? Nothing I tried works properly.

I switched to Forge 4 days ago and am loving the speedups, however TiledDiffusion and TiledVAE is a core part of my workflow, especially with Noise Inversion which is sorely missing in Forge, unless I'm too dumb to find it. So suddenly not having them available slows me down overall. Not only that, the tiledVAE function of Multidiffusion let's you select slow encoder and decoder, which take considerably longer to process but reduce undesired artifacts significantly, without that tiled upscaling is almost impossible under some circumstances.

Multidiffusion extension also added DemoFusion in a commit yesterday which seems quite interesting.
It would be great if I could enable that extension in Forge, but every time I try it just disables again, even when I manually disable the built-in forge multidiffusion.

I am also in need of the full set of features from Multidiffusion and cannot seem to get it enabled, even after removing the built-in version.

I believe forge was coded to block this extension.
