# LED Tape

## Insert LED Tape Blueprint into level

## Replace Mesh

In the details panel, replace the default mesh with your own custom mesh.

Either make a mesh in an external modelling tool like Maya or Blender, or you can use Unreal's built in modelling tools to make your own mesh.

**Note: Mesh must have UVs spread between 0 and 1 across the X-axis.**

## Adjust Settings

Under the Carbon section, there are many settings that you can customize:

| **Number of Pixels** | Sets the total number of pixels (LEDs) stretched across the custom LED tape. This defines how many individual light points the tape will have. |
| -------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------- |
| **Intensity**        | Controls the brightness (Emissive intensity) of the LED pixels.                                                                                |
| **Material Index**   | Specifies which material slot on the mesh applies to the LED tape. Useful if the mesh has multiple materials.                                  |
| **Color Mode**       | A checkbox to enable or disable RGBW mode. When checked, each pixel uses 4ch (RGBW), instead of the standard 3ch (RGB)                         |
| **Channel Mode**     | Choose between 8 Bit (RGB,RGBW) or 16 bit (RRGGBB, RRGGBBWW) color modes                                                                       |
| **Smoothing**        | Toggles a smoothing effect on the pixel transitions. Creates a more gradual change in pixel effects                                            |
| **Mesh**             | Allows you to specify the model that the LED tape will be applied to.                                                                          |

## Patch LED Tape

Patch LED Tape like any other Carbon fixture, either manually in details panel, or use the Auto Patch tool.
