# Light layer

Choose Layer > Add Layer > Add Light Layer... to create a new Light layer.

After choosing this menu item, the new Light layer is visible in the Layers listbox. You can use this listbox to switch between layers.

By adding a light you illuminate the scene. This is very convenient because without lights everything would be black. In BluffTitler you can add as many ambient and point lights as you want. You can easily create effects ranging from a spooky atmosphere with a single point light, or a disco with multiple different coloured lights.
When high quality is turned on, the triangles of the 3D models are split into smaller ones, resulting in better lighting. You can turn high quality on with the menu item Settings > High Quality.

### Ambient Light

With the first layer listbox you can set the light type.
This example uses the Ambient Light

### Point Light

With the first layer listbox you can set the light type.
This example uses the Point Light

### Sparkles

It is possible to attach a particle layer to a light layer. This way you can make the light itself visible. Choose Layer > Attach Particle to active Layer... for this effect.
This example uses the Sparkle preset.

### Light Beams

With the Beam Length property you can add light beams to text and EPS layers. Note that you have to position the light at the other side of the text to create this effect.

### Shadows

With the Shadow property you can make Text and EPS layers cast shadows over themselves and all other layers.

# Light type

### Ambient Light

An Ambient light has no position and no direction, it illuminates everything the same way. The colour of the ambient light determines the background colour of the scene.

### Point Light

Point lights have a position and cast light in all directions, like a light bulb.

# Properties

### Position

The light position of the point light. By putting the light close to the surface you can simulate a spotlight.

### Light Colour

The colour of the light.
Note that the colour an object appears to have is the result of the combination of the light colour and the material colour. For example if you light a yellow object(255,255,0) with a purple light(255,0,255) it appears red(255,0,0) because that's the colour component they have in common.

### Intensity

The light intensity. Be careful with high intensities.

### Beam Length

The length of the lightbeams that are created by the silhouettes of the Text and EPS layers. Notice that the length of the lightbeam also depends on the distance to the light source.

### Shadow Intensity

The darkness of the shadows the light creates. A value of 0 means no shadows, 0.5 means the shadows are half transparent and a value of 1 creates opaque shadows.

### Shadow Colour

The colour of the shadows. Note that you have to use a Shadow Intensity value creater than 0 to make the shadows visible.

### Shadow Softness

The softness of the shadow.
