substance designer 3dView shadows not showing

shubham kumar

I can't see shadows in 3dview viewport  in substance designer 5 . Does anyone know any solution ?
I am using opengl normal map method since i am following ROGELIO OLGUIN 's substance designer tutorial . 
i have point light active but rotating it doesn't make any lighting changes because shadows doesn't appear  . HDR light is working fine .

Its working now i turned HDRI Exposure to -10 and increased point lights intensity to 10 . Is it Good?
