Thank you. I had to check a reference but I think I understand now. http://www.xmission.com/~legalize/book/download/05-Modeling.pdf pg. 168 "The vertex components are laid out in memory in the same order as the vertex components listed in the table, starting with the position component. #define D3DFVF_XYZ 0x002 #define D3DFVF_XYZRHW 0x004 #define D3DFVF_XYZB1 0x006 #define D3DFVF_XYZB2 0x008 #define D3DFVF_XYZB3 0x00a #define D3DFVF_XYZB4 0x00c #define D3DFVF_XYZB5 0x00e #define D3DFVF_NORMAL 0x010 #define D3DFVF_PSIZE 0x020 #define D3DFVF_DIFFUSE 0x040 #define D3DFVF_SPECULAR 0x080 #define D3DFVF_TEX0 0x000 #define D3DFVF_TEX1 0x100 #define D3DFVF_TEX2 0x200 #define D3DFVF_TEX3 0x300 #define D3DFVF_TEX4 0x400 #define D3DFVF_TEX5 0x500 #define D3DFVF_TEX6 0x600 #define D3DFVF_TEX7 0x700 #define D3DFVF_TEX8 0x800 #define D3DFVF_LASTBETA_UBYTE4 0x1000 Every FVF must include a position with one of the D3DFVF XYZ, D3DFVF - XYZRHW, D3DFVF XYZB1, D3DFVF XYZB2, D3DFVF XYZB3, D3DFVF XYZB4, or D3D- FVF XYZB5. The remaining FVF flags are all optional." D3DFVF_LASTBETA_D3DCOLOR is not present in the list above, but as, per include/d3d9types.h:#define D3DFVF_LASTBETA_D3DCOLOR 0x8000 it is last, I assume it would also come last?
