Felt is a work-in-progress editor for creating and editing trixel-arts - custom asset files in a video game FEZ.
Ultimately, Felt will be able to save and load both trile-sets and art objects conveted into *.fezts.* and *.fezao.* file bundles produced by FEZRepacker, allowing you to seamlessly mod the game by injecting created and edited assets with HAT Mod Loader.
In the most part, trixels are basically voxels, in that the bigger art pieces are made out of small grid-aligned cubes. However, unlike voxels, trixels can be colored differently on each side, allowing an artist to create more believable pixel-art when trixel-art is being projected onto the screen in the game. This is achieved by using a cubemap projection to color the created model. However, because of this solution, there are two major throwbacks of this format that you have to be aware of:
- trixel faces behind and in front of other trixel faces will always have the same color,
- triles and art objects always need to have an uniform size, otherwise cubemap could not be constructed.
This is a limitation of a format/game and not this software. In the future, this could potentially be changed by adding new projection system that a special HAT modification could support.
FEZ distinguishes two types of trixel-arts: triles and art objects.
Triles are meant to be stored in trile-sets, and used to build a bigger map by arranging them in a trile grid (same thing as tile grid, but in 3D), while art objects are additional decoration models, which aren't limited by the grid arrangement or size.
- Orbital camera control with ortographic mode for easy preview of each face
- Optimized generation of the trile mesh
- Tools for appending/removing regions of trixels with
- Tools for painting cubemaps on top of triles
- Trile properties configuration (name, size, actor type)
- Manipulation of trixel regions (selection, moving, rotating, flipping, copy-pasting)
- Saving and loading trilesets and art objects with appended trixel data
- Importing trilesets and art objects by generating trixel data from mesh
- Gallery of triles (for trile sets) and switching between them
- Different preview modes (wireframe, flat, shaded)
- Helper construction tools (like mirror mode)
The top-most directory of this repository functions as a Godot project. However, in order for it to work properly, you have to compile GDExtension library first, using SConstruct. For that, you should be able to simply run scons command in both extensions/godot-cpp and extensions directories. If that fails, roughly follow the Building the C++ bindings and Compiling the plugin sections of the GDExtension guide for potential solutions.
Once building is done, appropriate libfelt binaries should be in the bin directory of the Godot project.
