// Gstudio format matrices

float4x4 matWorldViewProj;
float4x4 matWorld;
float4x4 matMtl; // inverse transpose of matWorld (WorldIT)
float4 vecViewPos;


matrix matWorldViewProj;
matrix matWorld;
matrix matMtl; // see above
vector vecViewPos;


Note: To aquire the <WorldIT> you will have to do some matrix operations.
