Maybe something like this:
- Open the impasto sculpt template, select the thing, enter sculpt mode, sculpt away.
- Enter Rendered preview mode and adjust the shader in the shader editor.
- Configure Output location
- Render animation
- In SliceComp: Add → Input → Image Sequence.
- Hook up Image and Alpha like the existing sequence.
- Adjust the path on File Output node
- Adjust the crop and maybe disable one or both of the ellipse masks inside CropNode nodegroup (press M to mute on the corresponding Multiply node)
- Render animation
- In Krita, create an image with the same dimension as the slices
- Drag and drop a couple hundred images at a time (or all at once if your computer can handle it) and select to import as file layers
- Remove the bottom most paint/background layer so that you only have the file layers
- Export to gimp image hose (.gih) format
- Create mask from color
- Style: Animated
- Dimensions: 2
- 1st row: Rank 18 Anglular
- 2nd row: Rank 22 (number of crop nodes connected) Incremental
- Create mask from color
- OK
