This example demonstrates how to customize an existing material loaded from a glTF scene in Bevy. It leverages the bevy-scene-hook crate to replace specific materials during the loading process. Please note that this might not be the most elegant solution.
This solution involves three main components:
-
Mask Texture (
assets/Textures/mask.png):- A manually created texture that acts as a mask, determining the customizable part of the texture via the alpha channel.
-
Custom Shader (
assets/shaders/custom_material.wgsl):- An extension to the standard PBR shader that masks and colors specific regions of the base texture.
-
Plugin Implementation (
src/soldier.rs):- Loads the glTF scene.
- Hooks into the loading process to remove the original material and add a marker component to the targeted entities.
- Applies a custom material to the marked entities.
- Updates the custom color in the material based on input from the UI.
Feel free to provide any feedback or suggestions to improve this example further!
