Spotlights are a great way to highlight specific areas of your scene or to add some extra drama to your renders. They can be used to create a variety of effects, from subtle highlights to dramatic shadows. In this article, we’ll show you how to use spotlights in Nvision to create realistic and eye-catching effects.
The first step is to create a spotlight. To do this, click on the “Create” menu and select “Light” > “Spotlight.” This will create a new spotlight in your scene. You can then position the spotlight by clicking and dragging it in the viewport. The spotlight’s position, rotation, and scale can be adjusted using the Transform gizmo.
Once you’ve positioned the spotlight, you can adjust its properties. The most important properties are the intensity, color, and falloff. The intensity controls how bright the spotlight is. The color controls the color of the light. The falloff controls how quickly the light falls off as it travels away from the source. You can also adjust the spotlight’s cone angle, which controls how wide the beam of light is.
Customizing Spotlight Properties
In addition to defining the general properties of a spotlight, you can also customize its specific attributes to achieve desired effects.
Spotlight Size and Shape
The shape and size of the spotlight can be adjusted to create different effects. You can control the shape of the spotlight beam by selecting from a range of presets, such as round, square, or rectangular. The size of the spotlight can also be adjusted, allowing you to create a narrow or wide beam.
Light Distribution
The distribution of light within the spotlight can be customized to achieve different effects. You can control the spread of the light by adjusting the cone angle. A wide cone angle results in a more diffuse spread of light, while a narrow cone angle results in a more focused beam.
Offset and Rotation
The offset and rotation of the spotlight can be adjusted to achieve desired lighting effects. The offset allows you to move the spotlight’s position relative to its original location. The rotation allows you to rotate the spotlight around its axis, enabling you to achieve precise lighting angles.
To customize the offset and rotation of a spotlight, use the following table:
| Parameter | Description |
|---|---|
| Offset | Moves the spotlight’s position relative to its original location. |
| Rotation | Rotates the spotlight around its axis, enabling you to achieve precise lighting angles. |
Advanced Spotlight Techniques
Spot Radius and Intensity
Adjust the spot radius to determine the size of the illuminated area, and the intensity to control its brightness. Larger radii cover a wider area but reduce the intensity, while smaller radii concentrate the light but increase its intensity.
Spot Color
Customize the color of your spotlight to match the desired effect or scene. Choose from a wide range of colors, including white, colored tints, and gradients.
Multiple Spotlights
Utilize multiple spotlights to create complex lighting setups. Each spotlight can have its own settings for radius, intensity, color, and location, allowing you to achieve a variety of lighting effects.
Shadow Quality
Control the quality of spotlight shadows by adjusting the number of samples. Higher sample counts result in smoother and more realistic shadows, but may increase the rendering time.
Shadow Map Size
Increase the shadow map size to improve shadow quality, especially for large or distant objects. Larger shadow maps provide sharper and more detailed shadows.
Shadow Bias
Adjust the shadow bias to prevent shadows from bleeding onto objects. Positive values move the shadow away from the object, while negative values bring it closer.
Angle Limits
Define the angle limits within which the spotlight casts light. This allows you to create spotlights with specific coverage areas, such as a spotlight illuminating a specific object or area.
Flicker Reduction
Enable flicker reduction to minimize flickering artifacts that can occur when the spotlight moves or the scene changes rapidly. This feature ensures smooth lighting even in dynamic environments.
Shadow Fade Distance
Specify the distance beyond which the spotlight’s shadows gradually fade out. This allows for smoother transitions and prevents harsh shadows at long distances.
Spot Attenuation
Control how the spotlight’s intensity attenuates with distance, using either linear, quadratic, or no attenuation. Linear attenuation reduces intensity linearly with distance, while quadratic attenuation reduces it more rapidly.
