Vegetation Parameters

This topic references tools and features that are legacy. If you want to use legacy tools in Lumberyard Editor, disable the CryEntity Removal gem using the Project Configurator or the command line. To learn more about legacy features, see the Amazon Lumberyard Legacy Reference.

The following vegetation parameters can be accessed in the Terrain, Vegetation panel in the Rollup Bar for a previously selected vegetation object. You can adjust parameters for one or more selected objects.

Unless otherwise noted, parameters apply to newly added and placed vegetation assets only.

Size

Changes the size of newly placed vegetation objects. Use this to uniformly scale the vegetation, where 1 represents 100%.

SizeVar

Changes the limit of size changes for a set of newly placed vegetation objects of a single kind. Keep Size at 1 and set SizeVar to 0.2 to get a nice variation in sizes.

RandomRotation

Randomly rotates objects while you paint new vegetation objects. To create a more natural look and distribution, you can set up a RandomRotation in the vegetation objects when you paint them. This feature works only with the Paint Object tool.

AlignToTerrainCoefficient

Points the vegetation object away from the ground. When this effect is applied, vegetation on cliffs points away from the surface instead of growing straight up.

UseTerrainColor

Makes the individual object receive the color of the underlying terrain for a better match. Use this option to blend the grass with the underlying terrain color. You can also use this setting on other objects, but it works best with grass. This effect is especially useful for making grass appear to fade in the distance.

AllowIndoor

Enables the vegetation to be rendered within vis areas.

Bending

This value controls the bending deformation of the vegetation objects. It ranges from 0 to 100, with 0 representing no bending effect and 100 the maximum effect. This effect is based on the amount of environment wind (WindVector) in the level.

GrowOnBrushes

Controls the placement of objects on brushes.

GrowOnTerrain

Controls the placement of objects on terrain. Useful if you want them placed only on brushes.

AutoMerged

Enables AutoMerged system on this object. For more information, see Using AutoMerged Wind Bending Effects.

Stiffness

Controls the stiffness of selected vegetation and how much it reacts to physics for AutoMerged vegetation.

Damping

Determines how responsive the vegetation is to physics damping for AutoMerged vegetation.

AirResistance

Degree that vegetation resists air movement (wind). Similar to the Bending setting but specifically designed for AutoMerged vegetation.

Pickable

Allows the player to pick up the object.

Density

Adjusts the distance between individual objects that you create while painting new vegetation. The density setting ranges from 0 to 100. If your density setting is bigger than your brush radius, the vegetation will not be created, so always make sure you have a suitable brush radius.

ElevationMin

Limits the minimum height at which you can paint vegetation objects. For painting underwater vegetation, set this value to lower than the ocean; 0 is a safe option.

ElevationMax

Limits the maximum height at which you can paint vegetation objects.

SlopeMin

Limits the minimum angle of the terrain on which you can paint vegetation objects. 255 equals 90 degrees. When you specify a SlopeMin value higher than 0, you can no longer place objects on flat grounds.

SlopeMax

Limits the maximum angle of the terrain on which you can paint vegetation objects. 255 equals 90 degrees. When you specify a SlopeMax lower than 255, you can no longer place objects on very steep areas.

CastShadow

Makes the object cast a shadow based on the minimum selected Config Spec setting. For example, High won't work on Low or Medium specs.
