World Editor: Object Brush Scripted Tool – Arma Reforger

Object Brush is a scripted World Editor scripted Tool. It allows for quick terrain "painting" with entities, based on the set parameters.

To access it, click the paintbrush icon in World Editor.

Usage

• to generate Prefabs in the area
• and drag to generate Prefabs along mouse movement
• Alt + then to generate Prefabs along a straight line; Esc to cancel
• Hold Space to delete Object Brush-created entities (works with all control combinations above)

Settings

Object Brush

Name	Description
Radius	Brush's radius
Strength	Brush's strength, value being in entity per hectare (100×100m)
Scale Fall Off Curve	Define the scale's Fall Off curve - curve goes from centre to border
Density Fall Off Enabled	Enable Density Fall Off settings below Density Fall Off only works well for wid brush single click placements
Density Fall Off Curve	Define the density's Fall Off curve - curve goes from centre to border
Density Fall Off Subarea Count	Define the amount of sub-areas (internal sub-division for performance)
Override Brush	Remove previously Brush-placed entities
Objects Config	This is where objects to be created are defined - see the section below. An SCR_ObjectBrushArrayConfig config can be drag & dropped here. ⓘ Config examples can be found in Configs/Workbench/ObjectBrush.

Objects Config

Name	Description
Min Scale	Maximum scale the object can have - requires Override Randomization enabled
Max Scale	Maximum scale the object can have - requires Override Randomization enabled
Prefab	The Prefab to use
Bot Distance	unused
Random Pitch Angle	Random X angle ("looking down/up")
Random Roll Angle	Random Z angle ("barrel roll")
Vertical Offset	unused
Random Yaw Angle	Random Y angle ("direction")
Prefab Offset Y	Static value that will be added to the Prefab's Y position
Min Random Vertical Offset	-value..0 negative range of Y randomness (cumulative with Prefab Offset Y)
Max Random Vertical Offset	0..+value positive range of Y randomness (cumulative with Prefab Offset Y)
Override Randomization	If checked, Prefab will use: Min Scale / Max Scale Random Pitch, Random Roll, Random Yaw values Otherwise, Prefab's Library random values will be used
Weight	The selection probability weight; if set to zero, the Prefab is ignored
Align To Normal	Align the generated Prefab to terrain's normal (makes it perpendicular to the terrain)
Scale Falloff	Whether or not using Scale Fall Off parameters
Lowest Scale Falloff Value	Minimum scale value the Scale Fall Off can set

Obstacles

Name	Description
Avoid Objects	Avoid creating Prefabs where other entities are placed
Avoid Objects Detection Radius	Objects detection radius - can be zero
Avoid Objects Detection Height	Objects detection's max height (from the ground)
Avoid Roads	Avoid roads, using their RoadGeneratorEntity Road Clearance value
Avoid Rivers	Avoid rivers, using their RiverEntity Clearance value
Avoid Power Lines	Avoid powerlines, using their SCR_PowerlineGeneratorEntity Clearance value
Avoid Land	Avoid anything above ocean's level
Avoid Ocean	Avoid anything below ocean's level

Obstacles - Area

Name	Description
Avoid Forests	Avoid forests (areas with a ForestGeneratorEntity)
Avoid Lakes	Avoid lakes (areas with a LakeGeneratorEntity and with "Is Lake" checked)
Area Detection Radius	Area (forest, lake) detection radius from the first click Set to zero to detect all areas of the world, takes more time the first time (and more RAM)
