Enable – When enabled, instances in a range get turned towards a specified direction.

Target Object – Picks an object according to which the direction aligns. When a geometry object is picked, each instance gets oriented towards the center of the object’s bounding box. When a camera object is picked, each instance orients towards the camera.

Look Axis – Selects which of the model object's axis turns towards the direction.

Reverse Orientation Axis – When enabled, the reverse of the selected axis gets turned towards the direction.

Horizontal – When enabled, the selected Look Axis turns only within the plane which is perpendicular to the normal.

Falloff Distance – Specifies the range in which instances get affected by the Look At parameters. When non-zero, only the in-range instances get affected; otherwise, all the instances get affected. There is no effect when a sun object is picked. 

Falloff Curve - Sets the strength of the Look Axis option..

Example: Look At 

In this example, the sunflower objects are scattered along a plane and the Look At option is enabled. The VRaySun is assigned as the Target object, and it is moved along the sky as if it was setting over the horizon. The Horizontal option is enabled, allowing the sunflowers to rotate more realistically. Slide through the images to see the movement of the sunflowers.

Scale

...

Section
Column

Scales the instances From the given value To the given value continuously with randomized results. When Uniform Scaling is enabled, the X-axis values are applied on the whole Distribute-on target object. A Map 1 can be applied. RGB maps can scale axes individually ( Red = X; Green = Z; Blue = Y). Grayscale maps control the scale of all axes proportionally. See the Scale example below for more information on the Step, Uniform Scaling, and Preserve Model Scale. 

Map Mode – Determines how the map is interpreted to control the scale.

Map Fixed – Black areas of the map represent the From values. White areas of the map represent the To values. All values in between are on the grayscale spectrum. No randomization is applied.
Random Amount – Black areas of the map have no randomization applied. In white areas of the map, full randomization occurs. The From and To values represent the lowest and highest scale allowed for the randomization.

Map Axes – Determines which axes the Map is applied to.

Step – Determines a value for scaling that is applied to all instances. Values greater than the difference between To and From result in all instances scaling to the value of To.

Step Axes – Determines which axes the Step is applied to.

Uniform Scaling – When enabled, all instances in all axes are scaled according to the values of the X-axis.

Preserve Model Scale – When enabled, instances preserve the original scale of the Models object.
