# What does this FVF value in the FVFData block of an .X file equate to?

I'm trying to read and ultimately write a mesh from/to file. This mesh has 2 sets of texture coordinates. The second set I know are held within the FVFData{} block of the .x file. The second set of coordinates is the only data within this block...the block looks like this:

FVFData {
258;
60;
1050755713,
1060090006,
...
}


This is 30 sets of 2 floating point values...

258 is equal to 0x102... D3DFVF_TEX1( 1, 2-component vector ) is equal to 0x100... ...where does the extra 0x002 come from? is that just D3DFVF_XYZ..? ...why are they coupled for this data block when there is no position data in the block?

From the D3D9 headers (specifically, d3d9types.h), you can see that D3DFVF_TEX1 is indeed 0x100 and D3DFVF_XYZ is 0x2; that means the FVF for that line is equivalent to D3DFVF_XYZ | D3DFVF_TEX1.
