Synopsis

uniform [-attenuation float] [-directionX float] [-directionY float] [-directionZ float] [-magnitude float] [-maxDistance linear] [-name string] [-perVertex boolean] [-position linear linear linear] selectionList

uniform is undoable, queryable, and editable.

The transform is the associated dependency node. Use connectDynamic to cause the field to affect a dynamic object.

If fields are created, this command returns the names of each of the fields. If a field was queried, the results of the query are returned. If a field was edited, the field name is returned.

If object names are provided or the active selection list is non-empty, the command creates a field for every object in the list and calls addDynamic to add it to the object. If the list is empty, the command defaults to -pos 0 0 0.

Setting the -pos flag with objects named on the command line is an error.

Return value

In query mode, return type is based on queried flag.

Flags

Long name (short name)	Argument types	Properties
-attenuation(-att)	float
Attentuation rate of field
-directionX(-dx)	float
X-component of direction.
-directionY(-dy)	float
Y-component of direction.
-directionZ(-dz)	float
Z-component of direction
-magnitude(-m)	float
Strength of field.
-maxDistance(-mxd)	linear
Maximum distance at which field is exerted. -1 indicates that the field has no maximum distance.
-name(-n)	string
name of field
-perVertex(-pv)	boolean
Per-vertex application. If this flag is set true, then each individual point (CV, particle, vertex,etc.) of the chosen object exerts an identical copy of the force field. If this flag is set to false, then the force is exerted only from the geometric center of the set of points.
-position(-pos)	linear linear linear
Position in space where you want to place a field. The gravity then emanates from this position in space rather than from an object. Note that you can both use -pos (creating a field at a position) and also provide object names.

Flag can appear in Create mode of command	Flag can appear in Edit mode of command
Flag can appear in Query mode of command	Flag can be used more than once in a command.

MEL examples

uniform -dx 0 -dy 1.0 -dz 0.5;
// Creates a uniform field pushing in direction (0,1,0.5) for every
// active selection. If there is no active selection, it creates this
// field at world position (0,0,0).

uniform -e -att 0.98 uniformF;
// edits the acceleration value of the field uniformF
uniform -q -att uniformF;
// queries uniformF for its acceleration value
