Model tags are made up of multiple _model tags.
from raw model, export collison, physics, and render models seperately.
note: collision models must abide by the laws of halo's geometry (no open edges)
note2: physics models in blender can be defined as [$geometryname]
note3: render models are not bound by collision rules
Material names are derived from a shader tag of the same name.
within shader_collections, you are able to define shader collections.
e.g. [shader prefix] [dir of shader tags]
Shader tags determine textures within the game.
Shader tags in Blam 2 use shader templates.
I gotta experiment with these more
