Quad Tree Node Array - Level File
| Hex | Translation | Meaning |

| 01 00 00 06 | 3 | level 3 |
| AD DE | dead | not used |
| C1 1D 00 00 | 7617 | 7617 packages follow (one package is edged in black) |
| Below follows the first package. | ||
| 3A 09 00 80 | 2362, high bit | negative u, negative v child index |
| 3B 09 00 80 | 2363, high bit | positive u, negative v child index |
| 01 00 00 00 | 1 | negative u, positive v child index |
| 54 09 00 80 | 2388, high bit | positive u, positive v child index |
- Child index
- If the high bit is not set then the child index is the index of another quadtree node (into the same array). Otherwise it is the index of an OTLF entry.
- U and V meaning
- X aligned node - U = Y, V = Z
- Y aligned node - U = X, V = Z
- Z aligned node - U = X, V = Y
- Note
- The alignment of a node depends on the leaf face that referenced it because there is no orientation information in a quadttree node.
