Light layer

What can I do with the light layer?

With the light layer you can lighten your scene.

How do I create a light layer?

Choose LAYER > Add layer > Add light layer... to create a new light layer.

The new light layer can be selected from the layers dropdown to make it the active layer.


The installer comes with shows demonstrating the possibilities of the light layer. Choose FILE > Open show... and select a show from the BluffTitler/Media/Shows/Light folder.

To quickly switch between your own shows and the ones that come with the installer, click on the Personal and App buttons in the upper right corner of the file dialog.

Point light

With the first layer style dropdown you can set the light type.

This example uses the Point light


With the shadow properties you can make layers cast shadows over themselves and other layers. Make sure there's something the shadows can fall on. This example uses a picture layer.

You can prevent a layer to generate shadows by marking the Never generate shadows checkbox in the LAYER > Active layer properties... dialog.

The current version has 2 limitations: transparent pictures can't generate shadows and the camera can't stand in the shadow.

Soft shadows

Use the Shadow softness property to create soft shadows. Soft shadows are only rendered in high quality mode.

Light flare

You can make the light itself visible by loading a flare texture by pressing the Change texture... button.

By default the light is behind the camera so you might have to move it to make it visible.

This example uses the flare16.jpg texture and the Flare effect.


With the Beam length property you can add lightbeams to text, EPS, picture, model and sketch layers. Note that you have to position the light at the other side of the text to create this effect.

You can prevent a layer to generate lightbeams by marking the Never generate lightbeams checkbox in the LAYER > Active layer properties... dialog.

The current version has 1 limitation: transparent pictures can't generate lightbeams.

Multiple lights

You can create up to 4 point lights. This example uses a red, green and blue light.

Light layer style 1

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. You can override this by choosing FILE > Set background colour....

Point light

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

Light layer style 2

Click on the Change texture... button to load a flare texture. The default light position is behind the camera, so you might have to move the light to make it visible.

Flare is always visible

The light is always visible, even when it is behind another layer.

Flare is visible if light is visible

This is the realistic situation.

Flare is visible if light is invisible

This unrealistic option can be used for special effects.

Flare is always invisible

The light is never visible.

Light layer properties


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


The diffuse 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.

Specular colour

The colour used for specular highlights. If this property is (0,0,0), the diffuse colour is used as the specular colour.


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.

Beam range

The minimum distance to the light necessary to generate a lightbeam.

Beam colour

The colour of the lightbeam,

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. Warning: soft shadows are expensive.

Flare size

The size of the flare. Click on the Change texture... button to load a flare texture.

Flare colour

The colour of the flare.
