Regeneration based off DNA?

[h0rizons]

Is there any way to use the previous metadata / DNA to run off the same batch again? For example, if I wanted to make a "mutant" version of a collection I generated, could I redraw the layers and use the program to re-run the same batch?

The util script rebuildAll is built for this case.

To regenerate/rebuild a collection with "mutations",
Save the original _dna.json file that is output in the build directory (always back up the build directory)

then, change the artwork in your layers directory being sure the filenames remain exactly the same,
then, running the following will create a "mutated" collection

node utils/rebuildAll.js -s path/to/_dna.json
