SuperMatrixComponent
SuperMatrixComponent is used by segmented matrix lights. It manages the matrix mesh, matrix material, segment count, segment direction, per-segment colour, intensity, strobe, and optional real per-segment lights (always spot lights — there is no point-light option).
Parameters
| Parameter | Purpose |
|---|---|
| SegCount | Segment count, written into the material parameter; indexes are clamped to 200. |
| bUseUAxis | true segments along U, false along V. |
| StaticMeshMatrix | Mesh that carries the matrix material. |
| bTransparent | Whether to use the transparent matrix material. |
| MatrixTransform | Relative transform of the matrix mesh. |
| SegmentLightRadius | Attenuation radius for segment lights. |
| LightSpotDefaults | The whole default parameter group for segment lights, mapped in from the fixture definition's light defaults. LightSpotIntensity is the segment lights' intensity multiplier and Angle is the outer cone angle. Segment lights are always spot lights. |

LightSpotDefaultsapply only to this segmented-matrix light path: every other component uses the in-house cone light, which does not support them.
Notes
- Segment colors are written through material parameters; visible output depends on the matrix material.
- Enabling real segment lights increases the light count. Final performance depends on UE project settings and hardware.
- After changing the segment count, make sure the asset has rebuilt the corresponding segment lights.
