The primary benefit of using these effects is the reduction of manual labor in complex scenes. By using distance and altitude as variables, artists can create gradients of growth, natural-looking transitions at path edges, and varied seasonal appearances through simple parameter adjustments rather than re-scattering entire scenes.

Effects allow you to modify scattered items by stacking "filters" that calculate from top to bottom.

When you create a Forest object, the plugin generates a series of "Items." Each item has parameters: Position (X,Y,Z), Rotation, Scale, and Material ID. An is a script that modifies these parameters on the fly based on external data.

If you need a specific artistic effect—like a single red rose in a field of white roses, or fallen logs placed specifically by a riverbank:

Use an Effect to offset the animation of each proxy based on its position or a random seed. This creates a natural "wave" of movement across your field rather than a mechanical pulse. 2. Item Color Tinting by Texture

When scattering items with children (like a tree with separate fruit geometry), ensure your effects target the parent item to avoid separating the assets during random transformations.

Randomizing or sequencing the start frame of animated geometry.

To scale down trees based on their distance to a target object (like a house or a custom helper node), use a script that calculates distance and applies an inverse scale multiplier:

: Automate complex scattering behaviors that manual painting cannot achieve.

As items get very close to the camera, an effect can gradually fade them out (set their scale to 0) to prevent the "clipping" effect when the camera moves through a tree or bush. 4. Coloring and Material Effects
