## Parameters

### Tag

Parameter ID: `GV_WEIGHTMAP_INPUT_TAG`

Connect the desired tag to this port.

### Index

Parameter ID: `GV_WEIGHTMAP_INPUT_INDEX` · Range: [-2147483648..2147483647]

The values in the weight map are stored in the same order as the index values of the object's points. Therefore the first weight value in the list applies to point 0, the next weight value to point 1, and so on. To access the weight value of a specific point, pass the point's index number to this port. If you are not sure how many points the object has or how many entries there are in the weight map, you can find this out using a Point node.

An object's first Vertex Map tag is accessed. The first point (index = 0) is assigned a weight of 0.5 (i.e. 50%).

### Value

Parameter ID: `GV_WEIGHTMAP_INPUT_VALUE` · Range: [-∞..+∞]

Here you can set the point's weight. You can enter a value from 0.0 to 1.0.

### Value

Parameter ID: `GV_WEIGHTMAP_OUTPUT_VALUE` · Range: [-∞..+∞]

The point's weight value.

### Count

Parameter ID: `GV_WEIGHTMAP_OUTPUT_COUNT` · Range: [-2147483648..2147483647]

The object's total number of points.
