These settings control which line types and Sketch materials are used by the tag. They work in the same way as the settings of the same name in the Sketch and Toon post effect (see Sketch and Toon Post Effect).
An object’s unhidden contour lines.
A Fold is the edge between a front and rear polygon.
Overlaps are silhouette lines that overlap the mesh, or the difference between Fold and creases.
Non-smoothed object edges.
This renders the edges of two adjoining polygons that lie in a certain angle or within a certain rotational range to each other.
These are edges that only belong to a single polygon.
These are edges that belong to regions of a material assigned to a polygon selection.
Renders each individual edge.
Renders edges that are created when one object intersects another.
A triangulated line is rendered for each quad.
For objects in motion, lines can be calculated in the direction of motion.
Renders lines of equal angle or height.
Isoparms render lines of the same name from generated objects.
Splines will be rendered.
Particles will be rendered. Make sure not to place any objects into the Emitter.
The Combine mode enables you to merge line types in the following ways.
Each line type is created separately and rendered individually on its own layer. If more than one line type produces the same line when using effects such as transparency or patterns, you may notice unwanted results where the lines overlap. An example would be enabling Creases and Angle, which may create lines for the same polygon edges. When strokes are enabled in the Sketch material, the strokes will be limited to lines of the same type.
All line types that use the same Sketch material will be combined on a single layer. This helps to prevent overlapping (see None above). When strokes are enabled in the Sketch material, all line types in this layer are available for the strokes to draw along.
The line types are merged so that only lines which do not overlap between multiple types are created.
The enabled line types are merged to create lines that only exist in more than one line type; this is the opposite effect to Exclusive mode.
See Hidden Cull.
See Hidden Cull under Objects.
To switch off hidden lines, set Hidden Cull to Self and clear the Default Hidden box or local Hidden box.
These settings control which lines are visible and which are hidden. The Hidden Cull mode sets which objects in the scene are used to find out if a line is hidden. In the following examples, the visible lines are black, the hidden lines are red.
In Self mode, only the object which created the line is used to find out if the line is hidden.
Children mode uses the parent and its children to find out if a line is hidden.
Hierarchy mode finds the top-most parent and then uses the parent and all its children to find out if a line is hidden.
In this mode, the line is checked against all objects in the scene to find out if it is hidden.
This mode uses the objects in the Objects box to find out if a line is hidden.
See also Default Visible
Use the Default Visible and Default Hidden boxes to specify which Sketch material to use for visible lines and which to use for hidden lines (Drag & drop the materials from the Material Manager into the boxes). Leaving a box blank means those lines will not be rendered.
These are the default materials and they are used for all line types except those with their own materials specified in their Visible and Hidden boxes (to display the Visible and Hidden boxes, set Line Materials to Both).
Each box has a triangle button to its right which you can click to access the following commands:
The Outline Culling mode controls which objects will combine their outlines if they overlap.
Outlines are not combined between overlapping objects, but look up Self Culling.
Children mode combines overlapping outlines for the parent and its children.
Hierarchy mode looks for the top-most parent and then checks all children of that parent.
The overlapping outlines of different objects are combined.
Sketch and Toon combines the outline of each object in the Objects box with the outline of any other object it overlaps.
If Self-Culling is active each object’s outline will be combined with the total outline. This will also occur if Outline Culling is set to Self.
If Object is selected in the culling outline menu, objects can be placed via drag & drop into this field to be included in the calculation.
The Fold Direction setting defines which types of folds are created: all folds (Any), folds in the direction of front to back, or folds in the direction of back to front.
The Fold Direction can be useful if you notice many unwanted lines forming creases.
Generally the Fold Direction should be set to Any, otherwise it reduces the number of lines created, which can result in gaps.
The Min setting helps to prevent creases from appearing in flat parts of the mesh. Each crease is only created if the angle between its polygons is greater than or equal to the Min value.
The Min and Max values define the range within which angle lines are created.
The Mode defines whether to include or exclude Texture tags for edges around alpha maps or materials. Drag & drop the Texture tags into the Tags box.
If the Combine option is enabled, Sketch and Toon will combine the outline for any overlapping alpha maps.
This mode defines which objects are used to find out if there are intersections.
This mode only produces intersection lines where an object intersects itself.
Children mode checks the parent for intersections with its children. Hierarchy mode looks for the top-most parent and then checks for intersections with any children of that parent.
This creates intersections where any object in the scene intersects any other object.
Sketch and Toon checks the objects in the Objects box for intersection with any other objects in the scene.
Enable this option to switch on lines for where an object intersects itself.
Objects in this field will be included in the calculation.
Note that the movement lines are only displayed when the animation is rendered to the Picture Viewer (i.e., across multiple frames).
The number of motion lines to create.
Velocity mode creates motion lines based on the object’s current velocity — the greater the velocity, the longer the lines. The lines will only appear if the object is travelling at least as fast as the Threshold velocity.
Trail mode creates motion lines based on the object’s path. To limit the trail to recent frames only, enable the Limit option and set Trail to the desired number of frames.
The minimum speed at which motion lines will be generated.
Enable the Bias option if you want the lines to be zero length at the Threshold velocity, otherwise they will already have some length at the Threshold velocity.
These are lines drawn away from the object or polygon selection based on a 2D projection.
Creates from the line types enabled in the Sketch Style tag or the post effect.
Shapes are created along lines created for the object (e.g., creases, edges or splines; isoparms won’t work), which can be interpreted as a type of motion blur (even though nothing is actually blurred).
Enable the Curves option to creates curves along the motion.
Use the Curve Width setting to adjust the width of the curves.
Use the Curve Height setting to adjust the height of the curves.
Uses a spline object (the Spline LINK control). The spline is used from the XY plane with the dimensions of the Spline object (the object matrix is not used).
A spline object (not spline primitives) can be placed into this field per drag & drop. It will then be used as a movement guide.
Length is the scale for the velocity.
Varies the Length value.
Scale X scales the motion lines.
Scale Y scales the motion lines.
The Offset is the size of the gap between the object or polygon selection and the motion lines. Enable the Relative option to make the offset a percentage of the object’s size on screen — this is useful for objects moving towards or away from the camera.
Squash or stretch the motion lines as they get further away from the object or polygon selection.
Defines the strength of tapering along the X axis.
Controls the strength of tapering along the Y axis.
Use this setting to adjust the strength of the Fade Opacity option.
Thin out and fade the lines as they get further away from the object or polygon selection.
Use this setting to adjust the strength of the Fade Opacity option.
The following modes are available:
The Angle setting defines which axis is used.
In Position mode you can choose the axis along which the contours are created.
In case a given object contains several UVW tags, a tag can be specified using the Sketch Style tag (drag the UVW tag from the Selection tab into the UVW Contour field).
The Angle setting defines which axis is used. You can choose the X, Y or Z axis of the object or world coordinate system, or the view’s (i.e. camera’s) X, Y or Z axis.
This setting defines the range of rotation over which the contour lines will be created. 0° will result in a right angle to the selected axis.
These define the range of angles over which the contour lines will be created. 0° means planar to the axis chosen (see Angle above).
This is the number of contour lines to create.
In Position mode you can choose the axis along which the contours are created. You can choose the X, Y or Z axis of the object or world coordinate system, or the view’s (i.e. camera’s) X, Y or Z axis.
The Spacing mode gives you two ways to control the distance between contour lines: Relative mode and Absolute mode.
Relative mode sets the number of contour lines to create (Steps) and how far along the object they start and end (Min and Max).
Absolute mode sets the distance between each contour line (Step). The Offset value enables you to adjust where the contour lines start along the object.
Use the Variation value to vary the size of the gap between contour lines. The default value of 0 means no variation and the lines will be equal distances apart.
This rotates the axis on which the contour lines are based.
If the object has multiple UVW tags, you can specify which of these should be used via the Sketch Style tag (Drag & drop the UVW tags to be used into the Contour UVW box on the Sketch Style tag’s Selections tab).
Use this setting to define where a given line should start.
The Min and Max values define how far along the object the lines start (Min) and end (Max).
This is the number of contour lines to create.
There are two modes for controlling the length of the particle lines.
Velocity mode creates a straight line from each particle’s current position. The line is as long as the particle would travel in one second provided Velocity Scale is set to 100%. Use a higher Velocity Scale value to lengthen the lines or a lower value to shorten them. The line points in the particle’s current direction.
Trail mode creates lines for the trail (i.e. flight paths already travelled) of the particles. The Limit and Trail settings limit the length of each line to the most recent part of the trail. For example, to draw the trail travelled by the particles over the past ten frames, enable Limit and set Trail to 10 F.
Note for the Path Mode, the entire animation must be rendered in the Picture Viewer so the particles are visible.
From left to right:
Enables the Limit option.
If, for example, you want to render the path that was covered over the previous ten frames, activate Limit and set Trail to 10B.
Use this setting to define the length of the particle lines.
The On Death setting controls what happens to a line when its particle dies.
With these modes, each line remains or disappears respectively when its particle dies.
When each particle dies, its line gets shorter and shorter until it eventually disappears, like a train disappearing into a tunnel.
Each line fades out gradually after its particle dies.
The Fade value defines how long the line takes to fade out.
