-The '''Bin Mesh PLG''' section stores face data split according to material indices. It is typically stored inside the [[Extension_(RW_Section)|extension]] of a [[Geometry (RW Section)|geometry section]] and does not hold any child sections.
+The '''Bin Mesh''' plugin holds an optimized representation of the model topology.
 == Structure ==
-b - DWORD  - Face type (Apparently always 1, representing a triangle strip)
+  uint32       flags (0 = tri list, 1 = tri strip)
-b - DWORD  - Number of material splits
+  uint32       number of Meshes (numMeshes)
-b - DWORD  - Number of faces
+  uint32       total number of indices
-−
-The number of material splits defines the size of an array which directly follows the structure above. The structure of the array elements (''TMaterialSplitData'') links the material split index to the vertices of the geometry:
+  #repeat for numMeshes
-b - DWORD  - Number of vertices
+To decide if the file is an OpenGL file when reading, check the platform of the [[Native Data PLG (RW Section)|Native Data]] chunk.
-b - DWORD  - Material index
+When no vertex indices are stored here, the pre-instanced geometry uses no indices or they are stored in the Native Data.
