Forest | Pack Effects

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.

The most immediate effect of high packing density is . As trees grow in close proximity, their root systems intertwine, aggressively competing for limited soil nutrients and water. Simultaneously, their canopies shade one another, reducing photosynthetic efficiency. This scarcity of resources leads to "suppression," where weaker trees grow slowly, become spindly, and eventually die. While this natural thinning (self-thinning) is a normal successional process, excessive packing accelerates mortality rates, creating an abundance of fine, dead fuel on the forest floor. Consequently, the primary negative effect of high packing is a dramatic increase in wildfire risk . Dense stands create continuous vertical "ladder fuels" (from ground to canopy), allowing a surface fire to climb into a catastrophic crown fire that is nearly impossible to control. forest pack effects
