| :--- | :--- | :--- | :--- |
| 0x40 | 24 | Lights1 | The Lights1 structure containing ambient and diffuse light data. |

    *   `colc[3]` (u8): Copy of ambient RGB color.
    *   `pad2` (i8): Padding.

2.  **Diffuse (16 bytes)**
    *   `col[3]` (u8): Diffuse RGB color.
    *   `pad1` (i8): Padding.
    *   `colc[3]` (u8): Copy of diffuse RGB color.
    *   `pad2` (i8): Padding.
    *   `dir[3]` (i8): Light direction (normalized).
    *   `pad3` (i8): Padding.
