Wildcards v3 — Nested Brackets for Draw Things

A small upgrade to wetcircuit's original Wildcards script (v0.5) for Draw Things.

What's new in v3

Nested wildcards. The original script supports flat {option1|option2|option3} substitution. v3 adds support for nestedbrackets, resolved innermost-first — so you can bind a sub-choice to only one branch of an outer choice:

{long {brown|black} hair|short {blonde|red} hair}

This will only ever produce long brown hair, long black hair, short blonde hair, or short red hair — never long blonde hair. Useful whenever certain variations should only apply to certain branches (hairstyle + color combos, object shape + matching color palette, clothing type + season-appropriate fabric, etc.)

Improved randomization. Replaced Math.random() with a time-seeded mix that avoids the original script occasionally repeating the same pick several times in a row in short batches.

Duplicate avoidance. The script now tracks which combinations have already been generated in the current batch and tries (up to 20 attempts) to avoid exact repeats — so a batch of 10 gives you 10 different combinations whenever the option space allows it.

How to use

Same as the original: write your prompt with {a|b|c} wildcards directly in the Draw Things prompt field, run the script from the Scripts tab, set your batch count, and it generates one image per resolved combination, logging each resolved prompt to the console.

For nested syntax, just nest a second {...} inside one of the outer options — any depth works, resolved from the inside out.

Simple example

{cube {blue|black}|cylinder {yellow|red}}

→ always cube blue, cube black, cylinder yellow, or cylinder red — color stays bound to its shape.
