Region UI tweaks
Button to toggle focused inpaint mode for the active Layer/Region
This toggle is only available when using regions. It has two effects:
- Generation will only use the text prompt and control layers of the currently active region.
- The active layer's alpha/transparency is used as mask. (But a selection will override this.)
Live mode: Button to apply result in a new Layer
Without regions, this is a simple way to apply a Live result as a new layer instead of replacing contents, same as previous versions.
With regions, the new button will apply the result to the active layer only. This is in contrast to the regular apply, which usually changes things in a small area around the active layer, and "splats" results to all affected regions. If you want the splatting, but as new layers, simply put your region layers in a group.
Other Changes
- Fixed upscale tile layout computation for non-square aspect ratios #791
- Fixed control layers for regions not showing up in Live mode #788
- Fixed (non-region) control layers not being stored/loaded from .kra files #788
- Increased strength threshold where an Inpaint model is used for refinement to 80% (was 50%)
- Changed region tracking in Live mode to be more similar to how it works in Generation workspace
- Disabled auto-hide of control layers in Live mode
- Fixed mask layers (Filter Mask, Transform Mask, Colorize Mask) causing errors #788
- Fixed LoRA folder filter not working in mixed Windows/Linux setup #793
- Improved Undo behavior when applying results by replacing content (can now be undone, but requires 2 actions)
- Fixed active layer changing to a different region when applying results to more than one region
- Workaround for error due to document without active layer #805
- Trim generated layer names for exessively long prompts #804

Regions
This release allows you collect text prompts, reference images and control layers in Regions, which are linked to paint layers or groups.
- Restrict prompts to areas which are indicated by layer's content (alpha mask)
- Seperate subjects in your image without their descriptions getting mixed up
- Use regions you define as masks for inpaint
- Jump between subjects in your image without having to adjust text prompts each time
- Selections will automatically find the regions they cover when using Fill or Refine
- Live painting focuses on the region which is linked to the active layer
- Keep parts of the image you're not working on fixed
- Work with higher canvas resolutions than before
- Tiled upscale now effectively works with prompts by selecting matching regions for each tile
- Control layers and reference images work with regions!
- Manage complexity with region hierarchies (nested groups)
Thanks to @Danamir for getting this started!
Please watch the video to get started and let us know how it goes. Further tutorial and documentation coming when time permits.
Important
If you are using a custom ComfyUI installation, make sure to update. Latest version of comfyui-tooling-nodes are required.
Changes
- ⚠ Applying results in Live mode now replaces active layer content by default
- Adding a layer per region becomes messy really fast
- Create a group for your layer if you want "non-destructive" apply
- Maybe this will be an option in the future
- Canvas now resizes right away when upscale is triggered (required for correct behavior in some cases)
- Renamed "Blur" control layer to "Unblur" (it takes blurry input and tries to sharpen/add detail)
- Added download option for SDXL version of Unblur control layer
- Added option to select if Unblur is used for tiled upscale (with two strength presets)
- Added seed to generated layer name #727
Cloud
- Full support for regions
- Purchase options also available now for those interested

Sampler preset changes
There was quite a bit of confusion about the changes to samplers in the last release, and a few bugs too. This release will hopefully improve the situation!
The preset name now contains both:
- a descriptive part (default, fast, realtime, ...) which indicates what it might be good for and how it differs from other choices, especially for users who are not familiar with Stable Diffusion
- the technical implementation name of the sampler (Euler A, DPM++ 2M, DPM++ SDE, ...) which you may see mentioned when downloading custom checkpoints
There are two new entries:
- Alternative - Euler Ancestral with normal scheduler and step count
- Lightning Merge - Euler Ancestral with uniform scheduler and low CFG/steps
Related changes:
- "Special" Lora (LCM, Lightning, FaceID) are no longer filtered out, but a warning will be displayed if they are added manually #640
- These are added automatically when needed, eg. when choosing a sampler or control layer that requires them
- Improved error messages for samplers which require a Lora
- Don't auto-convert previous sampler settings to a preset that requires a Lora
- Fixed sampler preset choice not being persisted in some cases #649
- Custom preset link will now open the folder if the preset file cannot be opened
- Added link to format documentation in the custom preset JSON
Please check out the documentation on the Wiki for more information about Samplers and how to customize them!

Style Transfer
There are two new Control layer modes: Style and Composition.
They work similar to the "Reference" mode: the selected image acts as a sort of inspiration, and doesn't have to match resolution or aspect ratio of your canvas. The difference is that Style will extract mostly art style and colors, while Composition focuses on the structural layout.
Composition | Style | Result |
---|---|---|
Works best with SDXL. Probably need a different approach for SD1.5.
Important
If you are using a custom ComfyUI installation, make sure to update. Latest version of ComfyUI_IPAdapter_plus is required.
LoRA Search and Auto-Completion
Redesigned the LoRA selection into a searchable drop-down.
There is also an option to filter via folders (applies to all added LoRA).
And adding LoRA in the text prompt will auto-complete now.
Control Presets
This release adds Presets for some Control layer and Sampler settings. The idea is to have a lean, easy to use UI where users can switch between a few recommended configuration options. Presets can be customized for those who want full control (but it may require editing a text file).
Control layer strength is now adjusted with a single slider, from low influence to very strong effect. This will influence the weight as well as the start and end of the interval in which ControlNet or IP-Adapter are applied.
If you want you can also modify those individually. The presets are stored in presets/control.json
, it is recommended to copy it to the user data folder before editing.
Sampler Presets
Samplers can now be fully configured by choosing from a few pre-defined options.
As before, the number of steps and guidance strength can be tweaked in the UI. New: you can edit the presets or add your own, and choose from any sampler / scheduler which ComfyUI supports.
Other Changes

Per-pixel Strength Masks
This release slightly changes how selections masks are interpreted.
Previously they would be either 1 (selected) or 0 (not selected), with smooth transitions at the edges for blending.
Now you can create masks with any values in between to customize how much the image changes per pixel.
Original | Mask | Result |
---|---|---|
"spooky dense forest"
For example, if you paint a selection mask 50% white in a certain region, and set strength to 80%, the actual strength in that region will be half of 80% = 40%. This is also known as "Differential Diffusion" or "Soft Inpainting". You can allow more drastic changes in some regions and only small adjustments in others - with smooth transitions - in one generation.
Original | Mask | Result |
---|---|---|
"toxic waste, acid lake"
Hint: enable global selection masks in Krita to easily edit selection masks.
Streamlined Cloud GPU
I've been working on a streamlined online service for those who don't want to install or lack the hardware. It is not complete, but can be tested already. Please look for more information and leave your feedback in this discussion!
Note: Local offline will always be the option with the greatest flexibility. But it's not available to everyone, and sometimes convenient can be nice?
Sponsors
This project is happily eating all of my time, and it feels like it is only getting hungrier! 😵
So I've had to think about sustainability. Cloud GPU is part of that, but it's an experiment and won't appeal to everyone. If you like the project, please consider donating via GitHub ♥. Much appreciated!

Discard Images from History
For those images we'd prefer to have never happened. You can multi-select with Ctrl/Shift!
New location for User Data
User files such as settings, custom styles and logs are no longer inside the plugin installation directory. This has some advantages:
- Easier to do a clean update/reinstall of the plugin without losing your settings
- Allows system-wide plugin installation with per-user settings
The settings are now located in a subfolder of Krita's user data. Typical paths:
- Windows:
C:\User\<your-name>\AppData\Roaming\krita\ai_diffusion
- Linux:
~/.local/share/krita/ai_diffusion
- MacOS:
~/Library/Application Support/krita/ai_diffusion
Depending on your system the location may be different. You can find it via the "View Logs" link in the settings.
Experimental Features

Selection Fill & Expand for Stable Diffusion XL
While SD XL has been supported for a long time, its capabilities to seamlessly fill selections were very limited. SD 1.5 almost always had superior results. This release adds the inpaint model developed by Fooocus to dramatically improve results. All SD XL checkpoints, including custom downloads, automatically profit from the change.
The new model will be downloaded as part of the "Stable Diffusion XL" workload, make sure to select it in the installer if you want to make use of it!
New Inpaint Modes
This release introduces more nuanced actions for filling and expanding areas of the image.
This nudges generation into a certain direction depending on what you want to do. Works especially well for SD XL, but also improves consitency for SD 1.5. Some examples are below, you can read the full documentation here.
Selection | Result | |
---|---|---|
Fill | ||
Expand | ||
Add Content | ||
Remove Content | ||
Replace Background |
