For example, you could make deciduous trees more likely at lower elevations and conifer trees more likely at higher elevations on a mountain.
It lets you assign the pieces randomly, or according to various rules. This node is a powerful and flexible way to create the “piece” attribute used by Copy to Points to decide which model to copy onto each point. Use the Copy to Points node to copy the objects onto the points.Ĭopy to Points has a Piece Attribute parameter that chooses which of the set of models to copy onto each point based on the value of an attribute on the point. For example, a set of different types and shapes of trees to make a forest. Scatter and Align has many high-level controls for how to distribute the points, avoid certain areas, add variety in size and orientation, and so on.īuild the set of models you want to copy onto the points.

Houdini’s workflow for automatically creating large numbers of objects in a scene (such as trees in a forest, rocks and pebbles in a desert, or buildings in a city) is as follows:īuild the surface you want to scatter the objects across.
