Modify a Vertex Map Tag according to the points movement or their disposition.

This tool is a tag to add to your editable polygonal Object. Set a Vertex Map tag on parameters to calculate different weight, like the points movement speed, rotation speed, stretching or the mesh density.
It’s also possible to convert the weight to a point/polygon selection automatically.

A Vertex Map Effector for Mograph is included.

Note that the demo version is limited to the « Movement speed » Mode.

v 1.25 :
– Auto-correction of the Melting when the render FPS is different that the view FPS.

v 1.2 :
– German translation by Lothar Mai.
– Czech translation by Lubo Bezek.
– Increased speed of the Position Point mode.
– New Polygons and Edges modes for the Position mode.
– The Selection tag is now limited to the selection restriction.
– A Vertex Map tag newly created is renammed if an other Vertex Map tag already exists.
– The intensity of the Weight Map Effector is now adjustable in R15.

v 1.1 :
– R14 compatibility.
– Increased speed.
– Weight map displayed in the view.
– New Acceleration mode.
– Ability to use children objects for the target in Position mode.
– Ability to use the object points as a target in Position mode.
– Ability to calculate the deformation with respect to the initial state in the Speed ​​mode.
– The Min and Max values of the Density mode can be defined manually.
– Limitation to the selection works now in render.
– New method for the Melting value.
– New button to create a material with the weight map.
– Various bugs fixed.

Vertex Weight Tag :
Define the Vertex Map tag to change. Click on « New » to create one automatically.

Constraint to Selection :
Define the Selection tag to limit the weight map. It can be a points or polygons selection.

Mode :
Define the calculation mode of the weight map. See the differents modes below.
Note that the demo version has only the Movement speed mode.

Mode : Movement Speed
Generate the weight map according to the point position difference relative to the precedent frame. More a point move, more the weight is important.
Works only if the object is animated.

Mode : Rotation Speed
Generate the weight map according to the point normal difference relative to the precedent frame. More the point normal change, more the weight is important.
Works only if the object is animated.

Mode : Stretching Speed
Generate the weight map according to the point scale relative to the precedent frame. More the polygons around a point scale, more the weight is important.
Works only if the object is animated.

Mode : Acceleration
Generate the weight map according to the point different speed relative to the precedent frame. More a point moving quickly, more the weight is important.
Note that if the checkbox « Discern slowing » is enabled, the weight value will be 0.5 by default, tend to 1 if the points accelerates and tend to 0 if they slows.
Works only if the object is animated.

Mode : Position
Generate the weight map in function of the point position to a target (relative (object position), absolute (global position), or relative to a target object). More a point is near the target, more the weight is important.

Mode : Rotation
Generate the weight map according to the point normal to a target (relative (object position), absolute (global position), or relative to a target object). More the point normal is face to the target, more the weight is important.

Mode : Geometry density
Generate the weight map according to the polygons sizes around the points. More they are big, more the weight is important.

Mode : Thickness
Generate the weight map according to the thickness of the object behind the points. More the thickness is big, more the weight is important.

Target :
Define a target object for the Position and Rotation mode. Click to Add to create a new target object.
In Position mode, the target is like a proximal. In Rotation mode, the target is like a light.

Target mode :
Define if the weight is calculated according to the axis target or the points target. Works only in Position mode.

Include childrens :
Define if the childrens of the target are used. Works only in Position mode.

Ignore Null Objects :
Define if the Null Objects are used. Works only in Position mode.

Reset at frame :
Define the frame to reset the weight.

Use deformed object :
Define if the deformers are used for the weight calculation.

Relative points :
Only works in Movement speed mode and Rotation speed mode.
Define if the point position used for the calculation is relative to the axis object or the world.
In Movement speed mode, if set to relative, the movement of your object in the scene will not influence, only the point animation will be.
In Rotation speed mode, if set to relative, the rotation of your object in the scene will not influence, only the point animation will be.

Deformation relative to initial state :
Define if the calculation in the Speed’s mode is relative to the precedent frame or the frame of the initial state.

Discern slowing :
See Acceleration mode.

Max value :
Define the maximum value of the weight for each mode (except the thickness). Click on Auto to autimatically define this value.
For Movement speed mode : it’s the maximum moving distance from wich the weight will be max.
For Rotation speed mode : it’s the maximum normal’s angle from wich the weight will be max.
For Stretching speed mode : it’s the maximum different size between the polygons from wich the weight will be max.
For Acceleration mode : it’s the maximum speed from wich the weight will be max.
For Position mode : it’s the distance from wich the weight will be max.
For Rotation mode : it’s the maximal angle between the normal’s points and the target from wich the weight will be max.
For Geometry density mode : it’s the minimum and maximum values of the polygons sizes.

This value do the same effect that the contrast.

Brightness :
Increases or decreases the overall intensity of the weight.

Contrast :
Increases or decreases the overall contrast of the weight.

Melting :
Define the melting value of the actual weight and the frame precedent one.
Usefull only if the object is animated.

Melting method :
Define the calculation method of the melting.
– Average : the actual weight mix to the frame precedent one.
– Addition : the actual weight add to the frame precedentone.

Invert :
Invert the weight.

Create Selection Tag :
Save the points or polygons selection according to the weight. A Selection Tag is automatically created and updated.

Select : :
Define if the points or the polygons have to be saved.

Weighting min :
Define the minimal weight from wich the selection is saved.

Weighting max :
Define the maximal weight from wich the selection is no more saved.

Invert :
Invert the selection.

Display :
Changes the display mode in the viewport. Note that the Polygon display is a bit slow.

Size :
Changes the size of the points in Point display mode.

Always visible :
Set the display always visible even if the tag is not selected.

Gradient :
Set the gradient of the weight for the viewport.

Create a Vertex Map Effector :
Create a Python Effector using the Vertex Tag. To use, for example, with a cloner in Object mode.

Create a Vertex Map Material :
Create a material with a vertex map shader.

Licence :
Buy the plugin to receive your activation key and set it in this field. The demo version is limited to the Movement speed mode.
