- | These scripts load display lists within the [[banjo_tooie:model_data|model file]], with certain aspects, properties, and checks applied. They are found at the end of a model file. Commands 0x00 through 0x10 are identical to those in [[banjo_kazooie:geometry_layouts|Banjo-Kazooie]], so we list only new commands. Note that level and skybox models can only use the old commands, and will not respect bone indices. | + | These scripts load display lists within the [[banjo_tooie:model_data|model file]], with certain aspects, properties, |

+ | Almost all of the new commands involve enabling software lighting effects on some vertices. The lighting uses the model file's | ||
+ | list of vertex normals, allowing lighting to be combined with vertex colors. Other than environment mapping (setting texture | ||
+ | coordinates to simulate a reflective surface), effects aren't determined by the commands, and must be enabled by the object | ||
+ | logic or other game conditions. | ||
