Thank you for sharing.
Just a couple of points...
The value at Model+0x58 is a dword, and if it equals 1, the model is drawn through DrawPrimitiveUPs. This occurs once or twice during the recursive traversal of the hierarchy.
As for Model+0x5C, it represents another dword, typically set to 0, and points to an item within an array of render data. Each structure in this array is 0x5c bytes in size and contains at least two user-provided vertex data buffers for the DrawPrimitiveUP calls mentioned earlier, filtered by the condition Model+0x58. The second buffer is utilized, and the draw call is executed, only if Model+0x294 is true as well. This draw call is wrapped by special render state enable/disable code...
Hope this helps.
Keep up the good work.
