# Retro Diffusion style LoRAs — trigger-word reference

Local record of the RD style-LoRA trigger words, for reproducible ComfyUI
ideation prompts without round-tripping to comfy-dev. Canonical source is
`catalog/loras.yaml` on the ComfyUI box (irv-ml1); this is m03-dev's working
copy (from comfy-dev, thread 01M01PKJ5EAR…, 2026-08-15).

**Licensing (operator directive):** these weights are copyrighted,
licensed-for-use, **not-for-export** — fleet-internal only, no
redistribution / publish / serve. Ideation OUTPUT stays `_ph` placeholder
per the game asset policy. This file records trigger STRINGS (not weights),
but treat the whole capability as internal.

**How triggers work:** prepend the trigger token to the prompt to activate
the LoRA's trained style. Coverage = share of the LoRA's training captions
that led with that token (higher = more reliable). Derived from each LoRA's
kohya `ss_tag_frequency`.

## Reliable (coverage ≥ 85%)

| ComfyUI `lora_name` | trigger | coverage |
|---|---|---|
| `rd/1bit.safetensors` | `pixel1biticons` | 100% |
| `rd/flatshading.safetensors` | `pixelflat64` | 100% |
| `rd/frontfacing.safetensors` | `pixelfurniture64` | 100% |
| `rd/gameboy.safetensors` | `gameboy64` | 100% |
| `rd/gameboyadvance.safetensors` | `gba64` | 100% |
| `rd/gamecharacters.safetensors` | `duelystchar` | 100% |
| `rd/gameicons.safetensors` | `pixelicons64` | 100% |
| `rd/isometric.safetensors` | `isometric` | 100% |
| `rd/modern.safetensors` | `svportrait64` | 85% |
| `rd/neogeo.safetensors` | `neogeo64` | 100% |
| `rd/nes.safetensors` | `nes64` | 94% |
| `rd/playstation.safetensors` | `psone` | 100% |
| `rd/snes.safetensors` | `snes64` | 87% |
| `rd/tiling.safetensors` | `pixelmcblocks64` | 100% |
| `rd/tiling16.safetensors` | `pixelmcblocks64` | 99% |
| `rd/tiling32.safetensors` | `pixelmcblocks64` | 100% |
| `rd/topdown.safetensors` | `pixelbuildings64` | 94% |

## Weak-but-distinctive (verify on first use)

| ComfyUI `lora_name` | trigger | coverage |
|---|---|---|
| `rd/simplegeometric.safetensors` | `pixelflatoutlined` | 38% (coined token, likely real) |

## No trigger — style-from-weights, just load

- `rd/gamecharactersanime.safetensors`
- `rd/gamecharactersretro.safetensors`
- `rd/industrial.safetensors`
- `rd/nashorkimitems.safetensors`
- `rd/segagenesis.safetensors`
- `rd/uipanel.safetensors`

(24 total: 17 reliable + 1 weak + 6 untriggered.)

## Gotchas

- **All three `tiling*` LoRAs share `pixelmcblocks64`** — the token does NOT
  encode tile size (the weights do). Do NOT substitute `pixelmcblocks16/32`.
- **`isometric` / `psone` triggers disagree with their vendor stems**
  (`isopixel64-v2`, `psone64-v1`). Caption token recorded here leads 100%;
  if either underperforms, try the stem form as a fallback.

## For the U R M03 first batch

Likely-relevant: `duelystchar` (gamecharacters) and `gamecharactersretro` /
`gamecharactersanime` (no trigger) for M03/grunt/burster sprites;
`frontfacing` (`pixelfurniture64` — note: furniture-trained, verify on a
character) and `topdown` (`pixelbuildings64`) for camera; console-palette
LoRAs (`nes64`, `gameboy64`, …) for the hi-bit palette exploration.
