SceneNavi is a level editor for The Legend of Zelda: Ocarina of Time for the N64 written in C#, using .NET 4 and OpenTK. It is compatible with any uncompressed ROM of the game, ex. the Master Quest Debug ROM; other versions need to be decompressed to 64MB using ZDEC or a similar tool. Working with individual scene and room files, as opposed to editing inside the ROM, is also supported, given a supported ROM has been loaded beforehand.

Features (as of v1.0 Beta 9):

• Changing of room actors, loaded room object models, loaded special scene-wide object models, spawn points, transitions, waypoints and waterboxes
• XML-based “actor definition” system to simplify level editing, ex. by breaking actor properties down into human-readable options (*)
• Changing of scene and room parameters, ex. background music, nighttime SFX (WIP)
• Editing of room model vertex colors; editing of collision polygons and polygon types (WIP)
• Modification of certain data tables, namely the exit and scene tables
• Export and re-import of area title cards
• Support for custom maps created by the tools SharpOcarina and Hylian Toolbox
• Support for ROMs with spinout’s “z64tables” data table relocation hack
• Hopefully easy-to-use user interface, partially inspired by previous OoT editors like Utility of Time and SayakaGL
• In-program update function that checks for newer versions online

The full source code is available on GitHub and requires .NET 4, OpenTK (currently uses opentk-2012-03-15), QuickFont and Nini 1.1.0.

Release notes for v1.0 Beta 9 (”You’ve Got Shaders In My Fixed Functions!”):

• Added new GLSL-based combiner emulation, still missing certain rendering details (ex. automatic texture-coordinate generation for reflections)
• Added support for anti-aliasing and mipmapping in renderer; can be toggled from menu
• Changed application configuration to use Nini library instead of .NET Properties.Settings
• Fixed various bugs; combiner inaccuracies, display list caching, Scene TreeView generation, mesh header types, etc.
• Added experimental help system, displays help string in status bar when hovering over menu items; still needs work
• Various other OpenGL-related changes and additions (ex. extension checks)
• Various minor GUI changes (ex. status bar appearance, Options menu arrangement)

Proper documentation is currently work-in-progress and not yet included. Keep an eye on the SceneNavi Update Page for per-version changelogs and further updates!

(* only certain actors supported so far; other actors default to normal “number, position, rotation, variable” format)
