Forest Pack — Effects

Forest Pack Effects turn a scatter tool into a procedural powerhouse. By moving beyond the basic "General" and "Distribution" tabs, you gain the ability to create environments that feel organic, chaotic, and—most importantly—real.

At its core, the Effects panel is a scriptable layer that sits on top of your scatter. It uses a simplified version of C++ (similar to expressions in After Effects) to control the transform, ID, and visibility of every individual item in your Forest object.

On steep slopes, trees don't grow perpendicular to the ground; they grow toward the sky, often with a slight "lean" due to gravity or prevailing winds. forest pack effects

While Forest Color is great for randomizing maps, the Effects panel can link the color or scale of your items to a specific bitmap.

You can apply an Effect that blends the surface normal (the angle of the hill) with a world Z-axis (upright). This ensures your vegetation looks like it’s actually fighting for sunlight, not just stuck onto a mesh. How to Apply an Effect Select your Forest Pack object. Go to the Modify panel and find the Effects rollout. Click the Add (+) icon.

Standard scattering often leaves "half-trees" or awkward overlaps at the edge of your geometry. It uses a simplified version of C++ (similar

Use the Exclude by Boundary effect. It calculates the bounding box of your scattered items and removes anything that isn't fully contained within the area. This is essential for clean lawn edges or forest paths. 4. Lean and Gravity

Imagine scattering a forest where the trees get smaller and more "autumnal" in color as they reach a certain altitude or move closer to a specific spline. Effects allow you to drive these transitions with surgical precision. 3. Edge Trimming and Boundary Logic
