X File of arena section 2
Note: degenerate triangles that would usually not pass de-stripification are not removed, though they should be. Each frame corresponds to a subsection.

No idea what data means. Cant even use hw to read it all.
*Update: It gets even better... One more embedded array and different entry types.
struct Unknown_Array_1
{
dword Unknown[4];
};
struct Unknown_Array_2
{
float x;
float y;
float z;
dword unknown;
};
struct Unknown_Array_3
{
dword unk;
dword unk;
};
struct Unknown_Array_4
{
float x[4];
float y[4];
float z[4];
float r[4];
byte Unknown[16];
};
struct Unknown_Array_5
{
dword Unknown;
dword Unknown;
dword Unknown;
dword Unknown;
dword Unknown;
dword Unknown;
dword Unknown;
dword Unknown;
dword Unknown;
float xyz_3[3];
dword Unknown;
float xyz_3[3];
float Unknown;
};
struct Unknown_Array_6
{
float x;
float y;
float z;
float r;
};
struct DataType0
{
dword Unknown[9];
struct Unknown_Array_2 Unknown;
};
struct DataType1
{
dword Array_1;
dword Unknown;
struct Unknown_Array_1 Unknown[Array_1];
struct Unknown_Array_2 Unknown[Array_1];
byte Unknown; //always 1*
dword unknown[Array_1];
can't read this with hw, next section must align with end of byte* above on a 16byte boundary
dword unknown[Array_1];
can't read this with hw, next section must align with end of byte* above on a 16byte boundary
float unknown[Array_1];
can't read this with hw, next section must align with end of byte* above on a 16byte boundary

};
struct DataType2
{
dword Array_1;
struct Unknown_Array_5 Unknown[Array_1];
struct Unknown_Array_6 Unknown[Array_1];
};
struct DataEntry
{
dword EntryType; // 0, 1, 2 so far... all different....
float xyz_1[3];
float xyz_2[3];
float xyz_3[3];
float Unknown_Float;
***depending on type...***
struct DataType0 Data
or

The Array+1 is not always true....
The //Always 1 are not always 1. In such a case an entire section was missing.
Of the 4 beginning dwords. The second looks to be count.
The other 3 look to be controlling the arrays that appear.

Awesome! Looks like our mystery dword type is a custom type...
Here are binary representations of several values.
Update: Based on pattern, I assumed its a floating point value type. Especially since the first 16 bits match their existing 16bit floating point type.
1bit sign, 4bits exponent, 27bits mantissa
value = (-1^s)*(2^(e-7))*(f/0x8000000)
(this assumes denormalized)
s eeee fff ffffffff ffffffff ffffffff value

The idea that I had was basically make the STB and LEV meshes the same thing... only one single mesh, generated from a heightfield. The LEV walkable areas and navigation could be applied as a texture stage, kinda like how it was in AE. You could then paint on the textures. I've already done quite a lot of this and so the only thing I don't have is what does the STB require and how it relates to the LEV...
Couple more questions:
So the flora are completely separate from the terrain? Are they like any other object (houses, etc.)? Just simplified?
How about the ground textures? Multiple texture stages, etc.? Texture coordinates in the STB?
Busy!

For more info on the stb's mesh structure, just look at my dump above.
