Hi

This it’s my first tutorial for export 3d models from 3dmax and Gmax to IL-2.  In this tutorial will be about of the structure of the ascii .msh files.

This guide will be used for reference for my next tutorial Exporting 3D models to il2.

The mesh in il2 its formed for the main mesh, the levels of detail they are the detail of the model that you can see when the plane its near or far, Hooks this are boxes where appers the effects like fire or smoke, The Collision boxes they are used for the game engine for hit detection, and the shadows they are de meshes that form the shadows.

The code shows a example of a .mesh file.

Code: [Select]

[Common]      //Header of the Mesh file
NumBones 0
 FramesType Single
 NumFrames 1

[LOD]
40 //distance where its visible the main (0-40 meters its visible the main mesh)
60 //distance where its visible the main (40-60 meters its visible the LOD1)
150 //distance where its visible the main (40-150 meters its visible the LOD2)

//from 150-??? its visible the LOD3

//Hooks thats are boxes that show in game the effects like smoke or fire.
