``` ```
- the prompt can end with + - `top`, `left`, `bottom`, and `right` define the four corners of a rectangle
- top/left/bottom/right are integer pixels - must be integers
- will be rounded down to nearest 8 - will be rounded down to the nearest multiple of 8
- strength and feather are floats - `strength` defines the ratio between the two prompts
- strength > 10 replaces other prompt - must be a float or integer
- strength < 0 does weird things - strength should be between 0.0 and 10.0
- feather can be 0.0 to 0.5, reasonably - 2.0 to 5.0 generally works
- prompt can end with + to append the regular prompt - 10.0 completely replaces the base prompt
- < 0 does weird things
- `feather` defines the blending between the two prompts
- must be a float or integer
- this is similar to UNet and VAE overlap
- feather should be between 0.0 and 0.5
- 0.0 will cause hard edges
- 0.25 is a good default
- the region has its own `prompt`
- any characters _except_ `>`
- if the region prompt ends with `+`, the base prompt will be appended to it
- this can help the region blend with the rest of the image better
- `<region:0:0:1024:1024:5.0:0.25:small dog,+> autumn forest, detailed background, 4k, HDR` will use two prompts:
- `small dog, autumn forest, detailed background, 4k, HDR` for the region
- `autumn forest, detailed background, 4k, HDR` for the rest of the image

This makes your prompt less specific and some models have been trained to work better with some amount of skipping. This makes your prompt less specific and some models have been trained to work better with some amount of skipping.
