While many know Forest Pack for its ability to scatter millions of objects, its true power lies in its advanced system. These effects enable artists to procedurally manipulate scattering patterns, object properties, and transformation data based on complex parameters, bringing unparalleled realism and artistic control.
You can use the Effects panel to solve complex scattering problems that traditional maps cannot handle. Below are the most common practical applications. 1. Advanced Boundary Constraints
Break repetition by introducing mathematical randomness based on unique item seeds. Core Applications of Forest Pack Effects 1. Item Scaling and Rotation via Texture Maps
When describing these effects, use these specific terms found in iToo Software's guides to sound like an expert:
Assign any required scene objects (like cameras or helpers) to the parameters defined by the effect. Check to see the results update in your viewport. Best Practices for Using Effects forest pack effects
Plants don't just grow straight up; they react to slopes and light. "Lean on Slope."
You can force scattered elements to lean or tilt in response to a global vector, simulating heavy wind or growth patterns.
The keyword represents a paradigm shift in 3D environment creation. It moves you from a manual gardener to an ecosystem architect.
The true power of Forest Pack Effects lies in its dual-user philosophy. For iToo provides an extensive library of ready-to-use presets—like "Bend by Object" (which pushes grass down when a car drives over it) or "Repulsion" (which prevents objects from overlapping). For "Effects Authors," the system is an open playground where one can write custom expressions to solve specific production hurdles.

If you want scattered items to shrink as they get closer to a specific dummy object in your scene, the expression looks similar to this:
Adjust the available parameters (such as distance, falloff, or scale limits) directly in the UI. Writing Custom Expressions: The Basics
What (e.g., 3ds Max with V-Ray, Corona, or Arnold) are you currently using?
Click Evaluate . Now, as you move the target object closer to your scatter, the nearby items will shrink dynamically. Essential Built-In Effects Presets Below are the most common practical applications
, users can stack multiple effects in the rollout to combine different behaviors, similar to a layer stack in Photoshop. Library & Presets : Forest Pack ships with over 30 built-in effects (like Tint by Boundary ) so you don't have to write code yourself. Interactive Parameters
fpItem.scale : The size multipliers along the X, Y, and Z axes. fpItem.rotation : The orientation values.
Calculate the distance between fpItem.position and fpCamera.position . If the distance is less than a specific threshold, reduce the scale.
