| − | =Bin Mesh=
| |
| − | The [[Bin_Mesh_PLG_(RW_Section)|Bin Mesh]]'s chunk format is almost the same as in non-instanced DFFs. The only difference is that the indices are RwUInt16 (as used internally by RW) instead of RwUInt32.

| − | =Native Data=
| |
| − | | |
| − | The Native Data has no child Struct like on the other platforms and not platform information.

| − | == Indices ==
| |
| − | | |
| − | Each vertex attribute in an OpenGL shader has an index. The indices used by the mobile GTAs are the following:
| |
| − | | |
| − | 0 - vertex position
| |
| − | 1 - tex coord 0
| |
| − | 2 - normal
| |
| − | 3 - color
| |
| − | 4 - vertex weights (only used with skinned geometry)
| |
| − | 5 - bone indices (only used with skinned geometry)
| |
| − | 6 - extra color (only used with SA's extra color plugin)
| |
| − | | |
| − | = Skin =
| |
| − | | |
| − | The Skin chunk contains a Struct chunk with the following data:
| |
| − | | |
| − | RwUInt32 platform ID (2 for OpenGL)
| |
| − | RwUInt32 number of Bones (numBones)
| |
| − | RwReal matrices[numBones][16]
