This value is used to control the “smoothness” of the change in the goal forces as the weight changes from 0.0 to 1.0. This is purely an aesthetic effect, with no scientific basis. The higher the number, the smoother the change.
This field shows the name of the object. Use the slider beside it to set the goal weight for the object.
If you change any of the per-particle settings, this goal weight will no longer apply.
Makes the goal active. You must first create a goal object (Particles > Goal) to see this and the rest of the goal weight attributes.
When the particle system is being attracted to goal objects, these attributes are filled with data about the specific point on each goal object to which each particle is being attracted. You can view this information in the Particles tab of the Component Editor.
For the remaining attributes in this section, click the Create button to create them. The button changes to Delete. Then click Delete to delete.
Provides per-particle goal weights for the Nth goal object. Goal objects are numbered according to their indices in the particle system's sparse goalGeometry array. This ensures that per-particle goal weights will be preserved while goal objects are being added to and removed from the particle system.
If no per-particle goal weight is found for a particular goal object, then the standard goal weight value for that object (specified by the slider next to the object's name in the particle Attribute Editor) is applied to all particles. The dynamically generated goalPP attribute then acts as a weighting factor for the sum of all goal forces acting on each particle.
The world space coordinates of the points on the Nth goal object towards which each particle is being attracted.
The world space normals of the points on the Nth goal object towards which each particle is being attracted.
The U and V tangents of the points on the Nth goal object towards which each particle is being attracted. The tangent directions correspond to the directions of greatest increase of the U and V texture coordinates at the goal points.
