The D3DMATERIAL7 type specifies material properties in calls to the Direct3DDevice7.GetMaterial and Direct3DDevice7.SetMaterial methods.
Type D3DMATERIAL7
ambient As D3DCOLORVALUE
diffuse As D3DCOLORVALUE
emissive As D3DCOLORVALUE
power As Single
specular As D3DCOLORVALUE
End Type
To turn off specular highlights for a material, you must set the power member to 0—simply setting the specular color components to 0 is not enough.
