Add Modifier – Specifies objects to be used for generating projected areas of exclusion or inclusion of Scatter guests. These areas are projected along specified axes and determined by the dimensions of objects or splines included in this list. Scatter Area Modifier objects cannot be the same as the Scatter Host objects. Note that Area Modifiers are available only in Surface and Volume Scatter modes. Operation Include – only instances within the projected area are created. Exclude – only instances outside the projected area are created. Axis – Determines the plane of the area modifier projection along the X, Y or Z axis. Falloff Near – Determines the distance from the selected area modifier object where the falloff begins its effect. The falloff range is the gradual fading of the area modifier effect between 100% and 0%. Falloff Far – Determines the distance from the selected area modifier object where the falloff range ends and the area modifier loses effect. Scale – Scale factor affecting instances between the Near and Far Falloff distances. The value represents the effect strength at the end of the falloff range. For example, a value of 0.5 causes instances to have a scale of 0% at the Falloff Near distance gradually increasing to 50% at the Falloff Far distance. Note that a value of 0 negates the falloff effect altogether. Density – Density factor affecting instances between the Near and Far Falloff distances. The value represents the effect strength at the end of the falloff range. For example, a value of 0.5 causes instances to appear at a density of 0% at the Falloff Near distance gradually increasing to 50% at the Falloff Far distance. Note that a value of 0 negates the falloff effect altogether. |
