i am using directx11 , and i create light source ( parallel light source )and scene ( loaded from obj file ) , and every thing look correct but when i rotate some object in the scene , my light rotate too with the object , and i don't wont to rotate the light and keep it fixed .
i try to fix the problem by do something like this :
XMMATRIX light_rotat = XMMatrixIdentity()
/*render the light*/
XMMATRIX light_rotat = XMMatrixRotationY(timeGetTime()/3500.0f);
/* render scene */
