IVA Forge v1.0.0

Pre-release draft — pending final in-game validation and visual material.

IVA Forge is a browser-based editor for KSP internal cockpits (IVAs): view your crew cabins in 3D
and place props and MFD screens with drag-and-drop — no Unity needed. Everything is baked from your
own install; no game or mod assets are redistributed.

What's in this download

• Embedded Python runtime (python.org 3.12 + numpy/Pillow/matplotlib) — nothing to install.
  Double-click IVAForge.bat to start.
• Generators, 3D viewer and WYSIWYG prop editor (src/), community calibration data for 95
  cabins (calibrations/, CC-BY-4.0), prop-face corrections (propfaces/), English/Spanish UI
  (locales/), and the whole documentation in both languages: the README with the contributing
  guide inside it (README.md / README.es.md) and every guide in docs/ with its Spanish twin
  (user-guide, ivalayout-format, setup-format — each .md cross-linked with its .es.md).
• No assets bundled: the catalog is generated from your GameData on first run.

Highlights

Viewer and editor

• Walk any installed crew cabin from the pilot's eye, with the real hull, real props, real prop
  textures and RPM/MAS labels.
• WYSIWYG prop editor: prop library sorted into 16 shelves by what a prop is, drag-and-drop,
  move/rotate/scale gizmos with snap and a proportions toggle, multi-selection, copy/cut/paste
  (Ctrl+C/Ctrl+X/Ctrl+V) across cabins, magnetize-to-hull.
• Props go in facing you and land where you drop them; textures, labels and screens are no
  longer mirrored; buttons show their own label.
• Grouped actions — Design (save · load saved · restore original · clear all) and
  Apply & share — and a save that survives a re-bake because it records props by name, not by
  position.

It bakes what the game really loads

• Cabins are read from the configuration KSP actually serves, after ModuleManager has patched it —
  not from the .cfg on disk. In a typical modded install that is the difference between an editor
  showing the interior you fly and one showing the before picture (two crew cabins used to bake
  empty).
• Every entry of a part's IVA Switch menu is baked, the one your install loads is marked, and
  Activate this variant makes another one the default from the browser (with an undo; it takes
  effect on the next KSP start).

Writing to your game, safely

• Apply to game writes a ModuleManager patch to GameData/IVAForge/patches/ with a timestamped
  backup, one-click undo and revert-all. Original Squad/mod files are never modified.
• Every release is checked with a full export round-trip over all cabins: a patch that would not
  reproduce the interior it came from fails the build instead of reaching you.

Sharing

• .ivalayout — one cabin's layout as a small JSON (references only, with a missing-mod report).
• Share your whole setup — one file with the interior each part loads, your hull calibrations,
  your cabin layouts and your favourites, plus every mod it needs and the version you have.
  Importing shows a report before anything is touched (missing mods, version mismatches, cabins
  you don't have, and your own edits that would be replaced), applies only what differs, and has a
  clean undo. See docs/setup-format.md.
• Calibration contributions — two clicks export the cabins you calibrated, per mod or one by
  one, with your nick for CC-BY attribution. Separate channel from the setup package above.

Everything else

• English/Spanish UI that retranslates on the spot, without reloading — including the
  first-run baking screen and everything the bake and the bridge print to the console.
• Favourites, out-of-date detection per cabin, bake_log.txt for cabins that fail, and a local
  bridge log at %APPDATA%\IVAForge\bridge.log.
• Fully local — no network access at any point.

Requirements

• Windows (x64)
• Kerbal Space Program 1.12.x
• ModuleManager (not bundled — install via CKAN or its forum thread)
• Disk: ~1.5 GB free where you unzip it. The first bake takes roughly 10-15 minutes and produces
  about 1 GB under catalog/, deletable at any time; later runs re-bake only what changed.

Licensing
