Lighting and display
The inspector's Render tab holds the lighting and image controls for the model currently on screen. The same controls appear as persistent defaults in Graphics settings; see The Render tab for how the two relate.
Environment
| Control | Effect |
|---|---|
| Skybox | Draws the environment image behind the model instead of a flat background |
| Background Color | The flat background colour. Choosing one turns off the "follows appearance" behaviour for the session |
| Environment | Which environment image is used. A model that authors its own environment, such as a USD stage with a dome light, adds an entry for it at the top of the list |
| Image-Based Lighting | Lights the model using the environment image |
Key light
The key light is the primary directional light, equivalent to sunlight.
| Control | Range |
|---|---|
| Key Light | On or off |
| Intensity | 0 to 10 |
| Color | Any colour |
| Horizontal, Height, Depth | −1 to 1 each, forming the light's direction vector |
Colour and direction sit inside an Options disclosure.
Ambient light
| Control | Effect |
|---|---|
| Ambient Fill | A soft fill so that shadowed areas are not pure black |
| Intensity | 0 to 2 |
| Rim Light | An edge highlight that separates the model from the background |
Shadows
| Control | Effect |
|---|---|
| Cast Shadows | Shadows the model casts from the key light |
| Drop Shadow | Draws the key light's shadow on a transparent ground plane under the model |
| Strength | 0 to 3 |
| Softness | 0 to 4 |
Overrides
The Overrides section forces global behaviour that would otherwise be decided per material, which is useful for diagnosing an asset.
| Control | Options |
|---|---|
| Post-Processing | On or off, as a master switch over the whole post-processing chain |
| Backface Culling | Use Model, which respects each material's double-sided flag; Global On, which culls everywhere; Global Off, which draws everything double-sided |
| Alpha Mode | Use Model, or forcing every material through Opaque, Mask, Hybrid, or Blend |
| Transparency | Sorted, which draws transparent surfaces back to front, or OIT, order-independent transparency |
Advanced image controls
The Advanced disclosure holds three groups.
Display covers tone mapping and colour grading:
- Tone Mapping: Khronos PBR Neutral, Linear, Reinhard, ACES, or Filmic. Reinhard is the default.
- Exposure, −4 to 4
- Contrast, 0 to 2
- Saturation, 0 to 2
- Vibrance, −1 to 1
- Gamma, 0.5 to 2.5
Bloom covers the glow around bright areas:
- Bloom, on or off
- Intensity, 0 to 2
- Threshold, 0 to 4
- Radius, 0.5 to 3
Quality holds Anti-Aliasing, Shadow Quality, and Dither for this model, with the same options as Graphics settings.
Statistics
The Statistics disclosure reports live figures for the current frame:
| Row | Meaning |
|---|---|
| Frame Rate | Frames per second |
| CPU Frame | Milliseconds of CPU work per frame |
| GPU Frame | Milliseconds of GPU work per frame |
| Draw Calls | Draw calls issued this frame |
| Triangles Drawn | Triangles submitted this frame |
| Drawable | The viewport's pixel dimensions |
| Model Memory | GPU memory held by the model's geometry and textures |
| Program Memory | The application's physical memory footprint |
| GPU | The Metal device in use |
