Blueprint Spline Mesh Component Property Reference

This page contains a reference listing of properties available on Blueprint Spline Mesh Components. The properties displayed will be slightly different if the Blueprint Spline Mesh Component is selected in the Blueprint Editor, is a Root Component, or if the component is selected in the Level Editor.

Properties

Static Mesh

Property	Description
Static Mesh	Specifies the Static Mesh to render for this component.

Materials

Property	Description
Element #	Once a Static Mesh has been specified in the Static Mesh Property, a number of additional Material Properties will appear. These will be named based on the Material IDs applied to the Static Mesh.

Spline Mesh

Property	Description
Start Pos	Start location of spline, in component space.
Start Tangent	Start tangent of spline, in component space.
End Pos	End location of spline, in component space.
End Tangent	End tangent of spline, in component space.
Spline Up Dir	Axis (in component space) that is used to determine X axis for co-ordinates along spline
Forward Axis	Chooses the forward axis for the spline mesh orientation

Advanced

Property	Description
Start Scale	X and Y scale applied to mesh at start of spline.
Start Roll	Roll around spline applied at start, in radians.
Start Offset	Starting offset of the mesh from the spline, in component space.
End Scale	X and Y scale applied to mesh at end of spline.
End Roll	Roll around spline applied at end, in radians.
End Offset	Ending offset of the mesh from the spline, in component space.
Smooth Interp Roll Scale	If true, will use smooth interpolation (ease in/out) for Scale, Roll, and Offset along this section of spline.
Spline Boundary Min	Minimum coordinate along the spline forward axis which corresponds to start of spline.
Spline Boundary Max	Maximum coordinate along the spline forward axis which corresponds to end of spline.

Spline

Property	Description
Allow Spline Editing Per Instance	If true, spline mesh properties - StartPos, EndPos, StartTangent and EndTangent- may be edited per instance in the level viewport.

Physics

Collision

Lighting

Property	Description
Cast Shadow	is true.

Advanced

Property	Description
Affect Dynamic Indirect Lighting	Controls whether the primitive should influence indirect lighting.
Affect Distance Field Lighting	Controls whether the primitive should affect dynamic distance field lighting methods.
Cast Dynamic Shadow	Controls whether the primitive should cast shadows in the case of non precomputed shadowing.
Cast Static Shadow	Whether the object should cast a static shadow from shadow casting lights.
Cast Volumetric Translucent Shadow	Whether the object should cast a volumetric translucent shadow.
Self Shadow Only	When enabled, the component will only cast a shadow on itself and not other components in the world.
Cast Far Shadow	When enabled, the component will be rendering into the far shadow cascades (only for directional lights).
Cast Inset Shadow	Whether this component should create a per-object shadow that gives higher effective shadow resolution.
Cast Cinematic Shadow	Whether this component should cast shadows from lights that have bCastShadowsFromCinematicObjectsOnly enabled.
Cast Hidden Shadow	If true, the primitive will cast shadows even if bHidden is true.
Cast Shadow as Two Sided	Whether this primitive should cast dynamic shadows as if it were a two sided material.
Light as if Static
Light Attachments as Group	set in a parent.
Indirect Lighting Cache Quality	Quality of indirect lighting for Movable primitives.
Single Sample Shadow From Stationary Lights	Whether the whole component should be shadowed as one from stationary lights, which makes shadow receiving much cheaper.
Lighting Channels	Channels that this component should be in.

Rendering

Property	Description
Visible	.
Hidden in Game	Whether to hide the primitive in game, if the primitive is Visible.

Advanced

Property	Description
Texture Streaming	Property Description Force Mip Streaming If true, forces mips for textures used by this component to be resident when this component's level is loaded.
LOD	Property Description Min Draw Distance The minimum distance at which the primitive should be rendered, measured in world space units from the center of the primitive's bounding sphere to the camera position. Desired Max Draw Distance Max draw distance exposed to LDs. Current Max Draw Distance The distance to cull this primitive at. Allow Cull Distance Volume Whether to accept cull distance volumes to modify cached cull distance. Detail Mode If detail mode is >= system detail mode, primitive won't be rendered.
Render In Main Pass	If true, this component will be rendered in the main pass (z prepass, basepass, transparency)
Receives Decals	Whether the primitive receives decals.
Owner No See	If this is True, this component won't be visible when the view actor is the component's owner, directly or indirectly.
Only Owner See	If this is True, this component will only be visible when the view actor is the component's owner, directly or indirectly.
Treat As Background for Occlusion	Treat this primitive as part of the background for occlusion purposes.
Use As Occluder	Whether to render the primitive in the depth only pass.
Render CustomDepth Pass	If true, this component will be rendered in the CustomDepth pass (usually used for outlines)
CustomDepth Stencil Value	Optionally write this 0-255 value to the stencil buffer in CustomDepth pass (Requires project setting or r.CustomDepth == 3)
Translucency Sort Priority	Translucent objects with a lower sort priority draw behind objects with a higher priority. Translucent objects with the same priority are rendered from back-to-front based on their bounds origin.
Lpv Bias Multiplier
Bounds Scale	Scales the bounds of the object.
Use Attach Parent Bound	If true, this component uses its parents bounds when attached.

Mobile

Property	Description
Receive Combined Static and CSM Shadows from Stationary Lights
