{{description>Create cap meshes for volume extends with options for normal inversion, holes, and UV customization. Perfect for capping volumes in 3D models.}}
====== Volume Caps ======
<note>This component is used in example scene(s) such as:

23_CGTube, 27_CGVariableExtrusion, 50_EndlessRunner.</note>
Creates flat cap meshes at the open ends of a [[..:datatypes#Volume|Volume]]. Optionally accepts additional volumes to punch holes into the caps.

===== Slots =====

==== Inputs ====
^ Name ^ Type ^ Description ^
| Volume | [[..:datatypes#Volume|Volume]] | The volume to cap |
| Volume[] (Holes) | Array of [[..:datatypes#Volume|Volume]] | (Optional) Volumes whose cross-sections are subtracted as holes from the caps |

==== Outputs ====
^ Name ^ Type ^ Description ^
| VMesh[] | Array of [[..:datatypes#VMesh|VMesh]] | The cap meshes |

===== Settings =====

==== General ====
Controls which ends receive caps and basic mesh options.

=== Start Cap / End Cap ===
Whether to build a cap at the start or end of the volume:
  * **Yes** - always build the cap
  * **No** - never build the cap
  * **Auto** - build the cap only if the volume is not closed (i.e. the cap would be visible)

=== Reverse Normals ===
Flips the normals of the cap mesh.

=== Generate UV ===
When enabled, UV coordinates are calculated for the cap mesh.

==== Start Cap ====
UV and material settings for the start cap.

=== Swap UV ===
Swaps U and V coordinates.

=== Keep Aspect ===
Preserves texel proportions:
  * **Off** - no correction applied
  * **ScaleU** - U is scaled to maintain proportional texels
  * **ScaleV** - V is scaled to maintain proportional texels

=== UV Rotation ===
Rotates the texture on the cap.

=== UV Offset ===
Offsets the UV coordinates.

=== UV Scale ===
Scales the UV coordinates.

=== Material ===
The Unity material to apply to the start cap.

==== End Cap ====

=== Clone Start Cap ===
When enabled, all material settings from the [[#Start Cap]] are reused for the end cap. Disable to configure the end cap independently.
