Hi, I have a light class, in which the light is represented by a cone(mesh) and I want the light to shine in the direction the cone is pointing at. For example I want to rotate the mesh 50degrees on the X-axis and 30degrees on the Y-axis. And I don''t know how to get the Direction member of D3DLIGHT8 to match the mesh''s direction accordingly.

Transform the "direction" vector of the light by the same matrix you use to rotate the mesh and it will work.
