hi, when I use an asymmetric ies profile on corona light, sometimes I need to rotate the ies profile. it is not comfortable if I have to rotate the light manually when the target light isn’t straight to the axis.
what i mean about ies rotate feature is similar like in the max photometric light.
This is a good idea.
But just to make sure - you know about rotating things in local coordinate system?
i must be very stupid, cuz I don’t know about that.. would you like to share something or some link about how to rotate things in local coordinate system? 
thanx romullus
yeah, it makes things easier
