Struct MaterialLoader 

pub struct MaterialLoader;

Asset loader for material descriptor files (.mat.json).

Parses a JSON descriptor into a MaterialAsset and declares shader and texture dependencies via LoadContext.

JSON Format

{
  "name": "brick_wall",
  "shader_path": "shaders/pbr.glsl",
  "uniforms": {
    "roughness": { "type": "Float", "value": 0.7 },
    "base_color": { "type": "Vec4", "value": [0.8, 0.3, 0.1, 1.0] }
  },
  "texture_slots": {
    "albedo": "textures/brick_albedo.png",
    "normal": "textures/brick_normal.png"
  }
}

Example

use goud_engine::assets::{AssetServer, loaders::material::{MaterialLoader, MaterialAsset}};

let mut server = AssetServer::new();
server.register_loader(MaterialLoader::default());

let handle = server.load::<MaterialAsset>("materials/brick.mat.json");
