With the light layer you can lighten your scene.
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.
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.
You can prevent a layer to generate shadows by marking the Never generate shadows checkbox in the LAYER > Active layer properties... dialog.
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.
You can create up to 4 point lights. This example uses a red, green and blue 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 lights have a position and cast light in all directions, like a light bulb.
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.
The light is always visible, even when it is behind another layer.
This is the realistic situation.
This unrealistic option can be used for special effects.
The light is never visible.
The 3rd dropdown sets the shadow algorithm.
Projected shadows, or fake shadows, are super fast and can handle transparent textures and morphing effects, but only render shadows on the floor. Set the vertical position of this floor with the Shadow plane position property.
When using a mirror layer, make sure the position of the mirror layer matches the Shadow plane position property and use the Not clipped style.
When using a picture layer as the floor, use the 3D in background style.
Stencil shadows, or volume shadows, can render shadows on all surfaces of other layers, but are slower, can't handle transparent textures and morphing effects and the shadows are rendered incorrectly if the camera stands in the shadow.
In contrast to projected shadows, stencil shadows need other layers to generate shadows. And the layer that receives the shadow must write to the depth buffer. For example, picture layers must use the 3D in 3D space style to receive shadows.
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.
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.
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.
The minimum distance to the light necessary to generate a lightbeam.
The colour of the lightbeam,
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.
The colour of the shadows. Note that you have to use a Shadow intensity value creater than 0 to make the shadows visible.
This property is only used when using Projected shadows. It sets the vertical position of the plane the shadows fall on.
The size of the flare. Click on the Change texture... button to load a flare texture.
The colour of the flare.
