Design levels in TrenchBroom and import them into your Unity game with zero manual configuration - and even allow players to create and share their own levels!If you are using URP, HDRP, or another Scriptable Renderer, you may need to convert the sample project's materials in order to fix "pink materials" from showing. To do this, select the materials and use Edit > Rendering > Materials > Convert (to URP or HDRP).Outside of the sample, Tremble supports any rendering pipeline agnostically.No matter what kind of game you're making, you'll need to make levels or maps. Whether you want to streamline your greyboxing workflow or fully produce levels using tried and tested editors like TrenchBroom, Tremble will import your Quake format maps instantly and precisely into Unity.Or what about allowing your players to create their own levels for your game? Whether you want to support Steam Workshop or Unity's User Generated Content (or even roll your own!), Tremble optionally supports players loading their own maps at runtime without any extra setup!Tremble removes every piece of friction possible, so that you can get creating within minutes and not have to deal with manually configuring map texture folders and Quake entity definitions (FGDs) yourself - it just brings your Unity materials and prefabs in automatically!Note that, although Tremble is not designed to import maps from other games (like Quake, Half-Life), it does have a Map Repair function which will try to fix maps up so that they work with your game. Map Repair supports geometry and entities, but will often import very strange UVs, as it doesn't have the original textures for reference.With Live Update, you can even make map edits while your game is in playmode - test out quick changes with ease!Just install Tremble, create a new map from inside Unity, and you'll be creating in no time!See Technical details below for the full list of supported features!Join our Discord server at: https://discord.gg/aUTmYxbVHZNote: Tremble is not affiliated with, or sponsored by id Software or the authors of TrenchBroom.Quake is a registered trademark of id Software LLC.Half-Life, Steam, and Steam Workshop are trademarks or registered trademarks of Valve Corporation.Tremble is an asset importer for Quake-style .map files, that works in Editor and at runtime.Full feature list:Support for TrenchBroom v2023 and v2024 on Windows, Mac, and Linux (Linux support is only tested on Ubuntu 22.04 LTS)Supports TrenchBroom features such as layers (including omitting layers marked as "omit for export")Support for Unity 2021.3+ (Tremble will run faster on newer versions as additional optimisations are available)Syncs to your map editor when compiling code (optional)Automatically imports maps on save from your map editorAutomated generation and installation of game config and FGD files for TrenchBroomOptional support for importing maps at runtime in Standalone buildsAllow your players to create their own maps and import them!Works with Steam Workshop, Unity User Generated Content, and more (though you'll need to write the Steam/other backend specific code yourself to download/upload maps using the revelant SDK)Support for "template" map files - create a single template to base all maps on to save initial work setting up common entitiesSupports point and brush entities from maps, mapped to MonoBehavioursEntities can be groupedEntities have full collision, UV2 for lightmaps, and are baked as static when appropriateFully supports prefabs:Prefabs are displayed in your map 1:1 with UnityEntities can be parented to other entitiesFully supports member variables/[SerializedField]s on entitiesSupported for prefabs and all other entitiesSupports basic types (string, int, float, bool, etc)Supports enumsSupports custom types (extendable by user)Supports references between entities in mapSupports ScriptableObjects - so you can wire your data up directly in mapsFully supports materials:Materials are displayed in your map 1:1 with Unity (including custom shaders)Materials can be grouped for ease of use"Special" coloured or checkerboard textures can be generated for your map editor for use with volumes and other invisible entitiesLive Update (experimental):Edit your map while in playmode and see changes instantly!Map Repair:Swap out broken textures and entities from mapsChange every instance of a given texture in a map for another(experimental) Import map geometry and entities from other games!Import FGD files from other games to generate entity classesImport WAD files from other games to import texturesCustomisable naming convention for materials, entities, materials, and fieldsUse snake_case, UpperCamel, lowerCamel, Human-readable or preserve your naming as-is from UnityCustomisable import scaleBy default, 64 map units = 1 Unity meter, but you can use whatever makes sense for your gameUnder the hood, it comprises 4 major parts, Map Sync, Map Import, Map Repair and Live Update.Map Sync takes your Unity prefabs and materials, and creates a TrenchBroom "game" full of textures and entity definitions, and handles the installation and configuration of it. Within seconds, you can be editing a map full of your actual Unity assets in TrenchBroom! Map sync for a small project is instant, and for a medium-sized project takes around 2 seconds.Map Import takes your .map file from TrenchBroom, and converts it back to a Unity prefab, applying your original materials and spawning your linked prefabs into it automagically. In doing so it also optimises the map geometry to remove hidden faces and to combine faces wherever possible. Map import for a small project is instant, and for a medium-sized project takes around 2 seconds.Map Repair takes a .map file which has broken textures or entity naming, and fixes them using values from your Unity project. It can be used to make wholesale swaps of textures and entities, or even to bring in maps from other games while swapping in your own prefabs. Map Repair for a small map is instant, and for a large map (such as Quake's E1M1) takes around 5 seconds.Live Update watches for maps that are modified while your game is running (in playmode). When detected, it re-creates all worldspawn brushes, updates supported properties on all map entities, adds any newly-added entites in the map, and deletes any removed objects from the map. This enables quick iteration while the game is still running. Map Reinstance for a small project takes around 50ms, and for a medium-sized project takes around 1 second.At runtime, Tremble steps aside and has zero overhead whatsoever. You can query your map for entities quickly if needed, but Tremble does not contain any Update code in your game and is zero-cost at runtime.Supports all current Unity LTS releases (Unity 2021.3.x and above). When run against newer versions of Unity, additional optimisations are available and so it's recommended to use the latest LTS or Tech Stream release.NOTE: Tremble supports Windows, macOS and Linux. Linux support is currently only validated on Ubuntu 22.04 LTS, with TrenchBroom from the GitHub releases page (not via Snap).
