Format
The header for the light section is extremely simple and consists of the magic, 0xBABEDEAD, followed by two arrays of lights, preceded by their count.
Light
Lights are a 0x41 byte long struct and consists of the following:
| Offset | Type | Description |
|---|---|---|
| 0x0 | long | Light Type |
| 0x4 | float3 | Light Color |
| 0x10 | float3 | Position |
| 0x1C | float3 | Direction |
| 0x28 | float | Reference Distance |
| 0x2C | float | Spot Cutoff |
| 0x30 | float | Unknown |
| 0x34 | byte | Quadratic Cutoff |
| 0x35 | float | Light Factor |
| 0x39 | long | Distance Cutoff (bool) |
| 0x3D | float | Unknown |
| 0x41 | End of light | |
