How to use
Look for green nodes. These contains primary parameters.
Look for blue nodes. These contains parameters you may also want to change.
(optional) Change "Calculate Changes" group to handle what rule your images are populated by. By default, the workflow iterates through keywords for epiCPhotoGasm model.
Check Extra Options and Auto Queue checkboxes in ComfyUI floating menu, press Queue Prompt.
It will fill your grid by images one-by-one, and automatically stops when done. Note that Auto Queue checkbox unchecks after the end.
Known Issues
"DrawPieSlice" node only accepts ingerer angles. If your image count is not a factor of 360, you'll see little lines of background between images.
"ImageTransformPaddingAbsolute" node mistakes weight for height, and vise versa. It can be fixed at any moment, and the workflow will break (it can be easily fixed back).
