Note: The material6 definition was manually splitted across multiple lines

The above example is showing a simple "cube" with only 5 sides, the 6th side was detached and converted to a cockpit part. The cube has a texture applied on it. This body is functionally equivalent to Camera Dummy.

Syntax and structure

BOD body files are using the standard BOD syntax.

BOD body file

<material 1>
<material 2>
<material n>

<full body>
<reduced body level 1>
<reduced body level 2>
<reduced body level n>

Material

Example material block has following structure (this section needs to be rewritten to expain):

Body

Every body block has following structure:

<body size>

<vertex 1>
<vertex 2>
<vertex n>

<part 1>
<part 2>
<part n>
<body flags>

Part

Every part has structure:

<face 1>
<face 2>
<face n>
<part flags>

Face

<vertex index 1> <vertex index 2> <vertex index 3>
<flags>
<smoothing group ID>
<UV for vertex 1> <UV for vertex 2> <UV for vertex 3>

Whether the face definition contains smoothing group ID and/or UV coordinates depends on value of the flags field:

flags:

Bit field. Only two bits are used:

• FLAG_UV = 8 (UVW coordinates are present)
• FLAG_SGID = 16 (smoothing group ID is present)

Empirical data (and how old X2BC worked):

-1 

no smoothing group ID, no UV

-9 

no smoothing group ID, UV

-17 

smoothing group ID, no UV

-25 

smoothing group ID, UV
