 A vertex will be drawn at position (20, 98, -25). UV mapping will begin at -20 coordinates in the U axis and 20 coordinates in the V axis. This vertex will feature a color of #929292 with full opacity alpha of 0xFF or 255.

+===== Animation Setup ======
+The animation setup rigs bones to a model and anchors them to the origin, or the parent bone (0xFFFF). It is comprised of two sections: A header, and a bone setup.
+**Animation Header**
+^ Offset from Animation Setup ^ Value Syntax ^ Description ^
+| 0x0000 | [<color #22b14c>aa aa aa aa</color>] | Scaling Factor (float) |
+| 0x0004 | [<color #00a2e8>bb bb</color>] | Bone Count |
+| 0x0006 | [00 00] | Padding / Unk |
+**Example (74a8.bin, Slappa at address 0x2ca8):**
+''<color #22b14c>42 34 00 00</color> <color #00a2e8>00 19</color> 00 00''
+Sets the scaling factor as 45 (<color #22b14c>0x42340000</color>) and sets the bone count as 25 (<color #00a2e8>0x19</color>).
+**Bone Setup**
+^ Offset following Animation Header ^ Value Syntax ^ Description ^
+| 0x0000 | [<color #A946F2>xx xx xx xx</color>] | X Position of Bone (float) |
+| 0x0004 | [<color #00a2e8>yy yy yy yy</color>] | Y Position of Bone (float) |
+| 0x0008 | [<color #f50569>zz zz zz zz</color>] | Z Position of Bone (float) |
+| 0x000C | [<color #d1b219>ii ii</color>] | Internal Bone ID |
+| 0x000E | [<color #ff5703>pp pp</color>] | Parent Bone ID |
+**Example (74a8.bin, Slappa at address 0x2cb0):**
+''<color #A946F2>BF 8E 23 70</color> <color #00a2e8>C3 2D 44 F0</color> <color #f50569>40 FC 92 09</color> <color #d1b219>00 05</color> <color #ff5703>FF FF</color>''
+Assigns a bone to the model at coordinates (<color #A946F2>-1.11</color>, <color #00a2e8>-173.27</color>, <color #f50569>7.89</color>), gives it an Internal Bone ID of 5 (<color #d1b219>0x5</color>) and connects that bone to Parent Bone -1 (<color #ff5703>0xFFFF</color>). This case just so happens to be the origin.

-Note that in order for textures to be animated, all texture data must be present and stacked sequentially.
