The roller coaster in the above screenshot is rendered with a sketch layer. The text layers are attached to the sketch. The template used is from BixPack 26.
With the sketch layer you can render animated handwritten texts and sketches.
Choose LAYER > Add layer > Add sketch layer... to add a new sketch layer.
The new sketch layer can be selected from the layers dropdown to make it the active layer.
The installer comes with shows demonstrating the possibilities of the sketch layer. Choose FILE > Open show... and select a show from the BluffTitler/Media/Shows/Sketch folder.
To quickly switch between your own shows and the ones that came with the installer, click on the Personal and App buttons in the upper right corner of the file dialog.
vector files for use in the sketch layer can be created with Bixelangelo.
You can load another sketch by choosing MEDIA > Change vector....
You can set the pen size with the Pen size property.
Use a negative value to render the inside for tunnels.
You can animate the sketch with the Writer property.
You can attach a picture by choosing LAYER > Attach layer > Attach picture to active layer....
The picture position and rotation are now relative to the tip of the sketch layer, as set with the Writer property.
You can attach a text by making the sketch layer the active layer and choosing LAYER > Add layer > Add text layer.
The text position and rotation are now relative to the tip of the sketch layer, as set with the Writer property.
You can attach a camera by choosing LAYER > Attach layer > Attach camera to active layer.
The camera position and rotation are now relative to the tip of the sketch layer, as set with the Writer property.
Attached layers are rotated 90 degrees, which is the common situation for texts attached to a 2D sketch. To follow a 3D sketch from the viewpoint of a roller coaster cart, use the following settings:
2nd layer style sketch layer: Attached layers follow sketch
Position property camera layer: (0, -2, 0)
Rotation property camera layer: (90, 0, 180)
Next to EPS files, the sketch layer also accepts bitmaps, like PNG, BMP, TGA and GIF files. The picture is automatically traced and turned into a vector.
You can trace another picture by choosing MEDIA > Change traced picture....
Best results are achieved when using a logo on a transparent background with a resolution of about 2000 pixels without small details at the edges. For logos without round edges the resolution can be smaller.
You can improve the quality by tracing a higher resolution picture.
The sketch layer also listens to the SETTINGS > Low/Normal/High quality menus.
Attached layer always point upwards.
Attached layers follow the curves of the sketch.
The attached layer is treated as a caterpillar tread: it rolls automatically when the sketch layer is moved.
The sketch is a closed at both ends.
The sketch is open at both ends.
The position of the sketch.
The rotation of the sketch.
The size of the sketch.
The width and the height of the pen.
This controls the way the pen size changes along the path. The 1st slider sets the radius at the beginning, the 2nd at the end and the 3rd slider controls the way the 2 values are interpolated. Set to 1 for linear.
For backwards compatibility, a different system is used when the 3rd slider is set to 0. In this case, the 1st slider sets the radius in the middle and the 2nd at the ends.
The rotation of the pen.
The diffuse colour of the sketch.
The colour used for specular highlights. If this property is (0,0,0), the diffuse colour is used as the specular colour.
The size of the specular highlights.
The transparency of the sketch.
A position offset relative to the orientation of the sketch points.
A roller coaster rail can be created with 2 or more sketch layers all using the same EPS, but with different offset and radius properties.
The extra displacement of the last point.
Animates the sketch. 1st slider controls the end position, 2nd slider the start position. This is in analogy with the same property of the text layer.
This value is added to the Writer property after applying physics. This can be used to keep a fixed distance between the cars of a roller coaster train.
The position and size of the texture.
Smoothes the sketch.
When this property is higher than 0, the sketch is rendered as straight segments of about the same length. This is useful in combination with the Special\WireframePlus effect.
This property is ignored when the Smooth property is used.
When the Gravity property is not 0, the sketch is animated with physics. Animate the Writer property at constant speed and BluffTitler does the rest. This can be used to simulate roller coaster cars, planes, trains and other vehicles.
Use a higher Gravity value to make the vehicle respond more to the ups and downs. Use a higher Friction value to make the vehicle slow down faster. The Minimum speed is used to prevent the vehicle from standing still or even moving backwards in badly designed roller coasters. The initial speed is set with the Initial speed property.
The start, end and duration of the animation is controlled with the keyframe positions and values of the Writer property.
This property can be used to solve sorting problems.
Layers have to be sorted according to their distance to the camera. This sometimes goes wrong when using very big, very small or irregular shaped layers. When this happens, use the Depth bias property to fix it.
