Era Modifier (Single)

Era Modifier is the pack's time machine. Twenty time-period descriptions - 1920s Art Deco, 1950s mid-century, the 1980s neon decade, Y2K, plus modern and futuristic - each appended to your base prompt by ID. Same subject, different decade. For anything nostalgic, retro, or deliberately period-styled, it's the single most effective dimension in the pack, because era words carry a huge amount of visual baggage in most checkpoints.

The modifiers span the twentieth century and beyond: 1 is "1920s Art Deco era, jazz age aesthetic, roaring twenties style," 2 is 1950s mid-century modern, 3 is the 1960s mod/space-age period, 4 is the disco 70s, 5 is the "1980s style, neon decade, retro-futuristic look," 6 is the 1990s pre-digital era, 7 is early-2000s Y2K, 8 is the 2010s, and the upper range covers modern and futuristic concepts. Each is a multi-clause phrase built to append cleanly: {base}, 1980s style, neon decade, retro-futuristic look. Combined with the pack's style transform (which has its own art-deco entry), you can push the same subject toward both a period and an aesthetic.

The inputs: text (base prompt), modifier_id (1–20, default 9), and preserve_base (default true). Note the default is 9, not 7 like most dimensions - so out of the box you're getting the upper era range, worth a glance before you queue a big batch. With preserve_base off, the node strips era keywords from your base text before appending, which matters when your prompt already says "vintage" or "futuristic." Output: single STRING, modified_prompt.

Mechanically it's the pack standard - a 20-entry table, a string append, zero dependencies, no models. Install: ComfyUI Manager → search "Variationator" → install → restart, or cd ComfyUI/custom_nodes && git clone https://github.com/MushroomFleet/ComfyUI-Variationator.git. (The repo's install-portable.bat references a requirements.txt that isn't shipped - nothing to pip-install.) It lives under Prompt Orchestration.

The best use is a time-travel batch: one base prompt through IDs 1, 5, 6, 7 gives you the same scene as Art Deco, 80s neon, 90s, and Y2K in a single pass - a genuinely useful reference set for retro projects. The honest caveat: era terms are some of the most checkpoint-dependent vocabulary in the pack. A model strong on 80s synthwave iconography will run with ID 5; a model that never saw period imagery will just give you a generic street. Test one or two IDs before committing, and don't stack two eras in one prompt - "1920s Art Deco" plus "1980s neon" is a contradiction that averages to neither.
