Make dir light to sun light problem

[kostenurka]

Hi there,

I have to make basic sun simulation but I can't link the Vray sun to move synchronized with Rhino sun. Few years ago I had no problems at all doing this;
My steps are:
1. create rhino sun with correct values
2. create vray sun
3. Make dir light to sun light (instantly this does not give to vray sun correct direction, nor later when animation run)

maybe I now miss something on the chain?! Any ideas?

Thank you
