Variables

  Type Name Description
Public variable bool AlignToSurface Whether the grass instances should be tilted to the normal of the landscape (true), or always vertical (false)
Public variable bool bAffectDistanceFieldLighting Controls whether the primitive should affect dynamic distance field lighting methods.
Public variable bool bCastContactShadow Whether the grass should cast contact shadows.
Public variable bool bCastDynamicShadow Whether the grass should cast shadows when using non-precomputed shadowing.
Public variable bool bKeepInstanceBufferCPUCopy Whether we should keep a cpu copy of the instance buffer.
Public variable bool bReceivesDecals Whether the grass instances should receive decals.
Public variable bool bUseGrid If true, use a jittered grid sequence for placement, otherwise use a halton sequence.
Public variable bool bUseLandscapeLightmap Whether to use the landscape's lightmap when rendering the grass.
Public variable FPerPlatformInt EndCullDistance The distance where instances will have completely faded out when using a PerInstanceFadeAmount material node.
Public variable FPerQualityLevelInt EndCullDistanceQuality  
Public variable FPerPlatformFloat GrassDensity Instances per 10 square meters.
