About art pass

(Updated 12/12/2019)

 

What is Art Pass

Art Pass is a function that represents the main line of illustrations added for the first time in 4.0.
By making the line texture of the illustration as it is, it can be handled like a vector line material on the model, allowing free deformation and color change expression while maintaining the line texture and thickness.

* For the Art Pass function, the target version of the model is “ SDK Can only be used with "No / Cubism4.0".
If you try to select the Art Path function with a target version other than the above, a warning pop-up appears in the lower right of the view area.

Nature and type of art pass

“LCNS” and “SNS” are used to generate art path lines.
The line shape changes even if the control point positions are the same.

How sprite drawing works

Explains the mechanism of line drawing when an art path is drawn with a sprite brush.
In the sprite method that uses textures prepared with multiple brush sizes, the texture size selected by the quality value of the brush setting changes.

The higher the quality, the larger the texture selected with a smaller line width.
The lower the quality, the smaller the texture with the larger line width.

The following adjustments were made to make the sprite drawing mechanism easier to understand. Sample model Outline of Hiyori Momose (video version).

  Quality: 5
Textures selected by line width overlap,
The area where the ink appears to overlap is drawn.

   Quality: 20
It is drawn with smooth handwriting.

In this way, the appearance of the line may change depending on the quality, so it is recommended to adjust to an appropriate value while looking at the art path actually drawn on the campus
For details on the sprite method, see " Artpath brush editing: Sprite method Please see.

 

Mechanism of mesh drawing

Explains the mechanism of line drawing when an art path is drawn with a mesh brush.
The mesh-type art path line has a special drawing mechanism as the number of control points increases.

The following is a mesh texture that has been adjusted to make the drawing mechanism easier to understand.

When drawing a straight line with this brush, I illustrated how the line changes depending on the number of control points.

2 points (AB)
The AB control points are in the same ratio as the texture looks. Moving one of the vertices will not change the depth ratio.


3 points (ABC)

It is the same as 2 points that the depth is set at the same ratio as the brush texture,
Moving the B control point, which is in the middle, changes the ratio of entering and exiting.


4 points (ABCD)

“In” is set between the control points of the first two points AB, and “Unplug” is set between the last two points CD.
“Intermediate” is displayed as it is between BC.


5 points (ABCDE)
From 5 or more points, it is drawn by the following mechanism.
“Enter” is set between the control points of the first two points AB, and “Done” is set between the last two points DE.
Between BC, “middle” and “middle (reversed horizontally)” are displayed.
“Intermediate” is displayed between the second and third CDs counted from the end.

The mechanism of 6 points or more is the same as the way of thinking at 5 points.
“In” between the first two control points and “Unplug” between the last two control points.
"Middle" is displayed between the second and third control points from the end,
“Middle” and “Middle (inverted)” are repeated between the other control points.

For details on the mesh method, see " Artpath brush editing: Mesh method Please see.

 

About art path scaling

Art pass is bounding box and Deformer The line width is maintained even when the scale is done with.
If you want to change the line width on the model, adjust the control point line width setting.

 

In the animator, select Properties Glue You can set the art path width magnification from [Place] & [Opacity].

 

* The width set for the border in the brush settings is maintained even if the magnification is changed.
* If the magnification is lowered until the edges touch each other, the magnification of the border will also be reduced.

About art path display

By default, the mesh line of the art path itself is displayed.
The mesh line can be edited or changed in color by editing [Art Path Display Settings: Mesh Line Color] on the [Tool Details] palette.

Types of control points

Control points for unselected art paths are displayed in white.
The control points of the art path where the start and end points are set are displayed in light blue.
The control points of the selected art path are displayed in red.
The control points of the art path with a polyline are displayed in yellow.
The control points for art paths that are set to follow are pink.

 

How to create an art path

There are two ways to create art paths.

Automatic generation of art path

This is a method to reproduce the "main line" as an art path on the model from the data in which the "main line" and "fill" are prepared in the original PSD.
Detail is" Automatic generation of art path "please look at.

 

Art path manual generation function

It is a method to create a line drawing by art path freely on the model.
Detail is" Creating an art path manually "please look at.
