Class { }::{ } is obsolete and must be removed (Class is abstract): NEEDS DESCRIPTION

{Actor} is obsolete and must be removed!: This warning is caused when there is an instance of a actor in a level that has been marked deprecated.

Actor {Actor} : Large actor casts a shadow and will cause an extreme performance hit unless bUseBooleanEnvironmentShadowing is set to true: A large actor has been set to cast shadows - this will cause extreme performance issues and should have bUseBooleanEnvironmentShadowing set to true.

Anisotropic BRDF and output velocity during base pass are mutually exclusive options

Sound {Actor} : Ambient sound actor has NULL AudioComponent property - please delete!: This warning is caused when there is a Ambient sound actor with a "None" AudioComponent.

{Actor} : Brush has NULL BrushComponent property - please delete!: This warning is caused when there is a Brush with a "None" ConstraintInstance component.

BSP Brush {Brush Actor} : Brush has zero polygons - please delete!: This warning indicates that you have a brush in the level that doesn't have any polygons associated with it.

Camera Camera has AspectRatio=0 - please set this to something non-zero

Run 'Clean BSP Materials' to clear {count} references: This warning indicates that there are material references on brush faces that aren't contributing to the BSP, and that applying the Tools->'Clean BSP Materials' operation can clean up these references.

{ActorName} has collision enabled but StaticMesh ({StaticMeshName}) has no simple or complex collision.

{ }::{ } is obsolete and must be removed (Class is deprecated): NEEDS DESCRIPTION

Level Duplicate level info: Two WorldInfos somehow exist...

{Count} element(s) with zero triangles in static mesh {StaticMesh}: TODO

Uncategorized Filename is too long ({FilenameLength} characters) - this may interfere with cooking for consoles.

Landscape {LandscapeComponent} : Fixed up deleted layer weightmap: TODO

{LandscapeComponent} : Fixed up incorrect layer weightmap texture index: TODO

Fixed up shared weightmap texture for layer {Layer} in component {Component} (shares with {Name}): TODO

Foliage in this map is missing {MissingCount} cluster component(s) for static mesh {MeshName}.

Foliage Foliage instances for a missing static mesh have been removed.: TODO

Hierarchical LOD System is disabled, unable to build LOD actors

{Actor} has invalid DrawScale/ DrawScale3D: This warning is caused when either DrawScale, DrawScale3D X, DrawScale3D Y, or DrawScale 3D Z is equal to zero.

Actor gas invalid hair strands material

{ActorName} has WorldTrace blocked. It will be considered to be world geometry

Virtual Textures {ObjectName} is using a virtual texture ('{TextureName}') on an unsupported property ('{PropertyName}').

Landscape ({ProxyName}) has overlapping render components at location ({X, Y}): TODO

Volume LevelStreamingVolume is not in the persistent level - please delete: This warning is caused when there is a level streaming volume that does not exist in the persistent level.

Lighting {Actor} : Light actor has NULL LightComponent property - please delete!: This warning is caused when there is a Light actor with a "None" LightComponent.

{LODActor} : Actor is missing.

Hierarchical LOD {LODActor} : Static mesh is missing for the built LODActor.

{LODActor} : NoActor is assigned. We recommend to delete this actor.

Lighting {LightActor} has same light GUID as {LightActor} (Duplicate and replace the orig with the new one): Duplicate and replace the original with the new one.

More overridden materials {Count} on static mesh component than are referenced {Count} in source mesh {StaticMesh}: TODO

{Volume} causes damage, but has no damagetype defined.: This warning is caused when there is a volume that is set to cause damage but doesn't have a damage type defined.

Map should have KillZ set.: This warning is caused when the map's KillZ in the WorldInfo properties is set to the default value.

No levels are associated with streaming volume.: This warning is caused when there are no levels associated with a LevelStreamingVolume, making it non-functional.

{Actor} : Brush has non-coplanar polygons: This warning is caused when there is a brush in the level that has non-coplanar polygons.

Particle System {Actor} : Emitter actor has NULL ParticleSystemComponent property - please delete!: This warning is caused when there is a Emitter actor with a "None" ParticleSystemComponent.

{Brush} : Brush is planar: Planar brush used - please note that this may not work well with collision.

PSysComp has an empty parameter actor reference at index {Index} ({Actor}): Param.Actor should not be NULL.

PSysComp has an empty parameter material reference at index {Index} ({Actor}): Param.Material should not be NULL.

Maps need lighting rebuilt: This warning is caused when lighting has been invalidated by moving or modifying a light actor.

Navigation Paths need to be rebuilt: TODO

Actors {Actor} : Repaired painted vertex colors: Painted vertex colors were repaired on this actor.

{Actor} in same location as {Another Actor}: This warning is caused when there is a actor that is in the same exact location as another actor.

Actor casts dynamic shadows and has a BoundsScale greater than 1! This will have a large performance hit: Serious performance warning...

{StaticMesh} has simple collision but is being scaled non-uniformly - collision creation will fail: Simple collision cannot be used with non-uniform scale.

{Actor} : Skeletal mesh actor has NULL SkeletalMeshComponent property: The specified SkeletalMeshActor has a NULL SkeletalMeshComponent.

{Actor} : Skeletal mesh actor has NULL SkeletalMesh property: The specified SkeletalMeshActor has a NULL SkeletalMesh.

Skeletal Mesh {Actor} : SkeletalMeshActor has no PhysicsAsset assigned.: In order for a SkeletalMesh to have an accurate bounding box, it needs to have a PhysicsAsset assigned in its SkeletalMeshComponent.

Ambient sound actor's AudioComponent has a NULL SoundCue property!: This warning is caused when there is a AmbientSound actor with a NULL SoundCue property.

Component is a static type but has invalid lightmap settings! Indirect lighting will be black.

{Actor} : Static mesh actor has NULL StaticMeshComponent property - please delete!: This warning is caused when there is a static mesh actor with a "None" StaticMeshComponent component.

Static Mesh {Static Mesh Actor} : Static mesh actor has NULL StaticMesh property: This warning is caused when there is a static mesh actor in a level with a NULL StaticMesh property.

{Actor} bStatic true, but has Physics set to something other than PHYS_None!: This warning is caused when an actor has its bStatic flag set to true but its Physics is set to PHYS_None.

{ObjectName} : Externally referenced

{Actor} (LOD {Index}) has hand-painted vertex colors that no longer match the original StaticMesh {StaticMesh}: It looks like the original mesh was changed since this instance's vertex colors were painted down - this may need a refresh.

{Actor} : Volume actor has NULL collision component - please delete: The specified volume actor has a NULL collision component and should probably be deleted.

{Actor} : Volume actor has a collision component with 0 radius - please delete: The specified volume actor has a zero radius for its collision component and should probably be deleted.
