Exlevel Helper Objects
You can create any helpers within the panel Create > Helpers > Exlevel.
On the Create panel, click Helpers, choose Exlevel from the list and then click Point, Plane, Box, Sphere, Cone or Wind.
Drag in a viewport to set the center and size of the helper object.
Point helper
The Point helper object is used as a starting point in the Point distributor, as well as the direction vector for modifiers: Vector direction, Vector orientation and Hard bend.
Vector size
Specifies the size of the vector icon.
Plane helper
The Plane helper object is used as a plane for the reflection and attraction in the Object reaction modifier, as well as a slice plane in the Object slice modifier.
Length/Width
Specifies the length and width of the plane.
Use front side
When on, the front side of the plane is used. The front side is on the side of the arrow.
Use back side
When on, the back side of the plane is used.
Infinite
When on, the plane is considered infinite, and Length and Width values are ignored.
Show calculation points
When on, the magnetic points are displayed on the plane in the viewport when Object reaction is used. Their number is adjusted by Steps on face in Object reaction.
Box helper
The Box helper object is used as a primitive object to reflect and attract in the Object reaction modifier, and to slice in the Object slice modifier.
Length/Width/Height
Specifies the length, width and height of the box.
Use front side
When on, the outer sides of the box are used.
Use back side
When on, the inner sides of the box are used.
Show calculation points
When on, the magnetic points are displayed on the box in the viewport when Object reaction is used. Their number is adjusted by Steps on face in Object reaction.
Sphere helper
The Sphere helper object is used as a primitive object to reflect and attract in the Object reaction modifier, and to slice in the Object slice modifier.
Radius
Specifies the radius of the sphere.
Use front side
When on, the outer sides of the box are used.
Use back side
When on, the inner sides of the box are used.
Show calculation points
When on, the magnetic points are displayed on the surface of the sphere in the viewport when Object reaction is used. Their number is adjusted by Steps on face in Object reaction.
Cone helper
The Cone helper object is used as a primitive object to reflect and attract in the Object reaction modifier, and to slice in the Object slice modifier.
Radius 1
Specifies the bottom radius of the cone.
Radius 2
Specifies the top radius of the cone.
Height
Specifies the height of the cone.
Use front side
When on, the outer sides of the box are used.
Use back side
When on, the inner sides of the box are used.
Show calculation points
When on, the magnetic points are displayed on the surface of the cone in the viewport when Object reaction is used. Their number is adjusted by Steps on face in Object reaction.
Wind helper
The Wind helper object is used as a wind generator in the Wind animation modifier.
Fan Size
Specifies the size of the fan in the viewport.
Wind Speed
Specifies the wind speed. Positive and negative values are possible.
Perturb Speed group
Allows to control the parameters of turbulence in the velocity, giving the fractal noise to the speed. As a result, the wind speed at different points of space varies.
On
This checkbox enables this turbulence mode, and, accordingly, these parameters become available:
Speed Amount
Specifies the maximum speed deviation.
Size
Specifies the size of fractal noise.
Iterations
Controls the number of iterations (or octaves) used by the fractal function. Fewer iterations use less fractal energy and generate a smoother effect. An iteration of 1 is the same as turning Fractal off. Range=1 to 10. Default=1.
Phase
Specifies the phase of turbulence. This parameter shows how fractal noise is shifted along the direction of the wind.
Note: The turbulence (fractal noise of speed) constantly moves in the wind direction, and with the speed equal to Wind Speed.
Perturb Vector group
Allows to control the parameters of turbulence in the wind direction, giving a fractal noise to it. As a result, the wind direction at different points in space varies.
On
This checkbox enables this turbulence mode, and, accordingly, these parameters become available:
Amount
Specifies the maximal deviation of the influence of the cross wind velocity vector. If this value is 0.0, the wind direction will not change. If the value is 1.0, the cross wind velocity vector is the same as the main vector of wind speed, and, accordingly, the wind direction may deviate by 45 degrees. The default value is 0.5.
Size
Specifies the size of fractal noise.
Iterations
Controls the number of iterations (or octaves) used by the fractal function. Fewer iterations use less fractal energy and generate a smoother effect. An iteration of 1 is the same as turning Fractal off. Range=1 to 10. Default=1.
Phase
Specifies the turbulence phase. This parameter shows how fractal noise is shifted along the direction of the wind.
Note: The turbulence (fractal noise of the wind direction) is constantly moving in the wind direction, and speed is equal to Wind Speed.
Decay group
Allows the user to adjust the wind speed variation with distance.
On
This checkbox enables this Decay mode, and, accordingly, these parameters become available:
Show
Displays the far attenuation range settings in viewports, the ranges appear as spheres. By default, Far Start is light brown and Far End is dark brown.
Start
Sets the distance at which the wind begins to fade out.
End
Sets the distance at which the wind has faded to zero.
Decay function graph
Allows the user to customize the decay graph.
