Trees¶

The Trees operation places terrain trees inside its mask. Where the mask is weaker, fewer trees are placed.

Source Prefab

The tree prefab. It's added to the terrains' tree prototypes when needed.

Density Per 100 Square Meters

How many trees per 100 m² where the mask is full.

Minimum Spacing

The smallest distance between two trees, in meters. It also limits how dense the trees can get: past that point, raising the density adds no more trees.

Seed

Changes the random placement.

Width Scale Range / Height Scale Range

The scale of each tree compared to its prefab, 1 by default. Turn on Random to give each tree a random scale between Min and Max.

Rotation Range Degrees

The rotation of each tree, in degrees. By default each tree gets a random rotation between 0 and 360.

How trees are placed¶

• Trees are placed after every stamp has shaped the terrain and cut its holes, stamp by stamp in Hierarchy order.
• No tree is placed on a hole.
• Minimum Spacing is kept from every tree already on the terrain: trees in the base and trees placed by earlier operations.
• The placement pattern is fixed in the world, so moving or reshaping a stamp doesn't reshuffle the trees that stay well inside it.
• A Trees operation only adds trees; it never removes any.

Plant a wood¶

1. Draw a stamp outline where the wood goes.
2. In Stamps, set the operation to Trees, or add a Trees operation to the list.
3. Set Source Prefab and Density Per 100 Square Meters.
4. To thin the trees out toward the outside, add a Border adjustment to the Spline Area mask.
