### Adjust 3D Model Scale

Source: https://github.com/egorshest/webgl-ascii-hero/blob/main/README.md

Example of how to adjust the scale of the 3D model within the React component. Change the numeric value to modify the model's size.

```tsx
<UserModel scale={8} />  // Change the number to adjust size
```

### Replace Demo 3D Model

Source: https://github.com/egorshest/webgl-ascii-hero/blob/main/README.md

Instructions to replace the default GLB model with a custom one. The code automatically references '/models/user-model.glb', so no code changes are needed if the new file is named the same and placed in the correct directory.

```bash
# Simply replace the demo file with your own model
# Make sure your file is named "user-model.glb" and placed in public/models/
# The code already references "/models/user-model.glb", so no code changes needed!
```

### Configure ASCII Effect Props

Source: https://github.com/egorshest/webgl-ascii-hero/blob/main/README.md

Customize the ASCII art effect by modifying props such as cell size, color inversion, character set, and tint color. Post-processing effects like contrast and brightness can also be adjusted.

```tsx
<AsciiEffect
  cellSize={9}              // Size of ASCII cells
  invert={true}             // Invert brightness
  color={true}              // Enable color
  characterSet="terminal"   // Character set
  volumeShading={true}      // 3D depth effect
  tintColor="#917AFF"       // Tint color
  postfx={{
    contrastAdjust: 1.8,    // Contrast
    brightnessAdjust: 0,   // Brightness
  }}
/>
```

### Modify Scene Lighting

Source: https://github.com/egorshest/webgl-ascii-hero/blob/main/README.md

Adjust the ambient and directional light sources in the 3D scene to control the overall illumination and mood. Different intensity values can be applied to each light.

```tsx
<ambientLight intensity={0.08} />
<directionalLight position={[2, 3.5, 6]} intensity={6} />
<directionalLight position={[-2, 1.5, 4]} intensity={0.35} />
```
