RPG Maker MV MZ Tileset Import Fixer - Autotile Sheets, Renamed Files, Shadow-Free Furniture Tool

The RPG Maker MV/MZ import fixer turns your legally purchased modern interiors pack into an MV/MZ-ready drop-in folder in minutes, so a corrupted Database import becomes clean tiles on the first try.

Dream outcome: point the tool at your bought pack folder and get back a Fixed/MVReady/ folder you copy straight into your project's img/tilesets/ + img/characters/ and import per the 1-page manual — fixed names, matched sizes, floor-friendly furniture, rotations, and real MV/MZ autotile sheets, instead of days of renaming and resizing across thousands of files.

Proof (exact counts and formats, measured 19.5s wall-clock on a 360-item / 1065-file LimeZu-structure fixture): 5 buyer files under assets/ — rpgmaker_import_fixer.py (standalone tool, Python, Pillow only) + import_manual.md (1 page, 23 lines) + credit_snippet.txt (copy-paste credit with [BRACKETS]) + import_matrix.csv (versioned v1.0.0, 14 rows covering MV 1.6.x + MZ 1.3.x) + requirements.txt (Pillow>=12,<13). Measured output on the fixture: 1065 renamed PNGs (sets/16x16|32x32|48x48/, category+label names) + 15-row missing-variant report (_reports/missing_variants.csv) + 160 shadow-free furniture variants (sets/shadowfree/, 0 gray px on all 160) + 60 rotation fills (sets/rotations/, 20 tables x rot90/180/270, all 48x48) + 12 $! furniture charsets (MVReady/img/characters/, 144x192, single-sheet no-shift) + 2 autotile sheets (MVReady/img/tilesets/TileA2_floors.png + TileA5_walls.png, 768x576 RGBA) + 354-file MVReady drop-in (352 renamed 48px tiles + 2 autotile sheets). Zip holds 8 files = 5 buyer assets under assets/ + README.md + LICENSE.txt + THIRD_PARTY.md. Selftest 58/58 PASS. Ships ZERO seller art — runs on YOUR legally purchased pack.

Time to first result: 5 minutes. The measured run is 19.5s wall-clock (300s budget); the rest is copying MVReady/img/* into your project and following the manual's Database → Tilesets step.

What you have to do: install Python 3 + pip install Pillow>=12,<13, optionally add labels.csv (file,label rows) in your pack folder for the category+label rename (without it names are kept and reported), run python rpgmaker_import_fixer.py --pack <your-pack> --out Fixed, read Fixed/_reports/missing_variants.csv, copy Fixed/MVReady/img/* into your project's img/tilesets/ + img/characters/, follow import_manual.md. Honest limit: MV/MZ engine drop-in is structural-only (48px tiles, 768x576 A2/A5 sheets, 144x192 $! charsets) — never tested inside the MV/MZ editor on the build machine, no engine installed. See import_matrix.csv for the exact tested file table.
