Glue

(Updated 11/01/2019)

Glue is a function that binds (adheres) the vertices of two ArtMeshes together.
First, please watch the video showing what can be done with the glue function.

Glue function terms

This section explains terms related to the function of glue.

Bind
Binding is the process of attaching the “overlapping vertices” of two ArtMeshes together.

Glue weight
The setting of which side of the two ArtMeshes the bound “overlapping vertices” are affected by.
Weights can be set per vertex, but not per keyform control.
Details are explained in “Adjusting Glue Weight” in the latter half of this page.

Compatibility
The degree of glue application is the degree of effectiveness of the glue setting.
Lowering the value of the degree of application weakens the effect of the glue.
Unlike weights, they cannot be controlled per vertex, but a numerical value can be set for each key form.
Details are explained in “Using the Applicability of Glue” in the latter half of this page.

How to set up glue

This section explains how to set the glue on the ArtMesh.
Below are comparison images with and without glue.

  Glue available Without glue

 

Here is the procedure for setting up the glue.

No.  Image Description
(1) 

Select the two ArtMeshes you wish to bind.
Click the [Edit Mesh manually] icon to enter mesh edit mode.

In edit mode, the Add Vertex tool is selected by default.

: Vertex Add Tool

When in mesh edit mode, the mesh lines of each ArtMesh are displayed in a different color.

How to operate when editing multiple meshes at the same time:
• Immediately after entering edit mode, both ArtMeshes are actively displayed.

• To deactivate, click on an empty space with the selection tool to make it unselected.
(You can also change to the selection tool while holding down Ctrl while still in the add vertex tool.)

: Selection Tools

• Clicking on an unselected area will display a pop-up window. You can select any ArtMesh from the pop-up to make it active.

• You can click directly on any ArtMesh with the selection tool to make it active.

(2) Re-strike the vertices of the area to be adsorbed with glue to “two overlapping vertices”.
Use an eraser or lasso tool to erase the vertices of the area to be adsorbed.
(3)

Add a new vertex to the area where the vertex was deleted.
If a vertex is added while both ArtMeshes are active, the edge will be the color of two overlapping colors.

A vertex with two overlapping edge colors is added to both ArtMeshes, resulting in “two overlapping vertices”.

Once you have inserted the vertices you want to glue together, it is convenient to click [Auto connect] to automatically connect the vertices.

(4)

Focus on each ArtMesh by itself and check to see if the mesh surrounds the texture and if any edges are left unconnected.

(5)

Select the vertex you wish to adhere and click on the [Tool Details] palette -> [Bind].
(Ctrl + G does the same)

[Binding] “two overlapping vertices” will cause the vertices to adhere to each other and change the color of the vertices.

Click the green check mark in the upper left corner of the view area to exit mesh edit mode.

 

Once the glue is set

1. A yellow “Glue” tag (2) appears on the view area.
2. A glue object is added to the [Part] palette. (2)

When a glue is locked in the [Part] palette, the tag turns gray and the glue cannot be edited.

TIPS
The glue objects in the palette can be shown or hidden using the Add Filter button (1) in the upper right corner of the [Part] palette.

TIPS
If multiple glues are set for a single ArtMesh, multiple “Glue” tags will be displayed.

 

Points to note when setting glue

When editing a mesh after setting glue, be careful to unbind the glue once and then edit the mesh, or the mesh shape may be incorrect.

Multiple glues can be set for a single ArtMesh.
For example, for the “torso” ArtMesh, you can set three locations such as “neck”, “right shoulder”, and “left shoulder”.

* Theoretically, as long as the vertices of the ArtMesh to which the glue is to be applied do not overlap, you can theoretically have as many glues as the vertices allow.

* But be careful not to duplicate the vertices to be bound, as this will result in unintended deformations and the glue will not function properly when embedded.
Be sure to set only one glue on the vertex to bind.

 

Adjustment of glue weight

The glue weight can be adjusted between 0-100%.
The table below compares the following conditions: no glue, 100% A weight, 100% B weight, and 50% A:B weight.

 

Without glue A weight 100% B weight 100% A:B weight 50%

Both A and B move to the left and right with the same amount of movement.
-
-
-

Since the movement of A has 100% priority, the object B is extended.

In this case, the weight of B is 0%.
-
-

Since the movement of B has 100% priority, the object of A is extended.

In this case, the weight of A is 0%.
-
-

The vertices, pulled and bound to each other, are midway between their original positions.

In this case, the vertices do not move because the amount of movement is the same.

 

The stronger the weight, the more priority is given to the object's movement.
By adjusting the weights, the shape can be cleaned up as shown in the following image.

 

No weight adjustment Weight adjustment available

 

About weight adjustment

How to adjust the weight ratio of two vertices

 

No.    Image Description
(1)

Select the ArtMesh with the glue set, or click on the glue tool (1).

Click the [Glue] tag (2) that appears to switch to the weight adjustment mode.

TIPS
You can also switch to the weight adjustment mode by clicking on the corresponding glue object from the [Part] palette.

(2)

In the weight adjustment mode, the degree of influence of the weights is displayed in color.

In the [Tool Details] palette, click [Glue Weight A: B] icon.

(3)

Drag the brush over the out-of-shape areas to trace and shape them.

Drag:
Strengthens the weight of the red ArtMesh.

[Shift] + drag:
Makes the weight of the green ArtMesh stronger.

Click on [Toolbar] -> [Arrow tool] and click on an empty view to exit glue weighting mode.

TIPS
The higher the % setting of the brush weight, the quicker the adjustment, but start out low and get used to the adjustment.
The larger the brush size, the wider the area to be adjusted, but it is recommended to start out small and make partial adjustments.

TIPS
After setting the glue, try moving the parameters that affect it and check carefully to make sure that the shape has not been lost.

 

How to adjust the weight (weight) ratio of a single vertex

The weights can be adjusted to separate bound vertices from each other.

 

No. Image Description
(1)

Click on the yellow “Glue” tag displayed on the ArtMesh where the glue is set, or click on the corresponding glue object in the [Part] palette to switch to weight adjustment mode.

To adjust the weight ratio of a single vertex, use the [Tool Details] palette -> [Glue Weight A] or [Glue Weight B].

(2)

By dragging vertices bound by glue with [Glue Weight A] or [Glue Weight B], vertices can be separated from each other.
Glue Weight A:
The weight of the red ArtMesh alone is made stronger, pulling away the adsorption of the vertices of the red ArtMesh.

Glue Weight B:
The weight of the green ArtMesh alone is made stronger, pulling away the adsorption of the vertices of the green ArtMesh.

(3)

Re-merge Glue Vertices Tool:
Vertices that are separated by a single weight adjustment can be returned to the vertex-absorbed state with the [Re-merge Glue Vertices Tool] icon.
You can also [Shift] + drag to evenly release the adsorbed vertices.

TIPS
Note that both functions will not be performed unless the vertices are within the brush size range.

 

Degree of glue application

The degree of glue application is the degree of effectiveness of the glue setting. Lowering the value of the degree of application weakens the effect of the glue.

Unlike weights, they cannot be controlled vertex by vertex, but can be controlled by keying parameters.

 

 

Delete glue

Click the [Glue] icon in the Parts Palette or on the View Area to confirm that the glue you want to erase is selected.

Press [Delete] or [BackSpace] to delete.

It can also be deleted by right-clicking the [Glue] icon in the view area and selecting [Delete].

TIPS
If you unbind vertices directly from [Manual Mesh Edit] to an already glued ArtMesh, an empty glue will remain.
In such cases, the same procedure as above can be used to delete them.

 

 

Check glue condition

You can check the glue status by clicking the [Glue Status On/Off Toggle] icon in the upper right corner of the view area.

 

 

 

Load when incorporating glue

The following is a comparison of the computational load when “Glue,” “Rotation Deformer,” and “Warp Deformer” are incorporated, in the following order.

Warp Deformer > Rotation Deformer > Glue
* Except for extreme cases such as binding all vertices with glue

The glue can be used to simplify parameter and deformer structure settings to reduce the weight of model data.

(Example)
• An object with glue set with two parameter assignments has a lower load than an object with three parameter assignments.
• The load is lower when a deformer with two parameters is set in one level of glue than when a deformer with two parameters is set in two levels of glue.
