Hi i have linked the hdri to corona sun as in this video tutorial from rommulus3d https://www.youtube.com/watch?v=eXvwkfVaeB4
But when i move the corona sun the hdri moves in the other direction, just like mirroring .
Im going nuts on this thing…
I think the solution would be to use (-U_Offset) or -360 in wire editor but I’m not sure.
Hi Maru, i have tried that , but it wont work or worse, it starts to behave weird…
attached anotehr screenshot and max file.The hdri can be replaced with any other one (using one of peterè right now)

I think this should link the movement of sun and hdr offset:
(degtorad U_Offset*360)+(degtorad 270)
where “270” is the corona sun’s “correction” like in Romullus’ tutorial.
It works for me but I’m not sure if there isn’t something utterly stupid in this code. 
not working here 
maybe some one has a file with a linked sun to and vray hdri (just to better control the hdri) 
-HorizontalRotation and -Rotation. Should work.
Romullus You are the man IT worked! Many THX im ultra new to all the parameter wiring
Me too. I’m just putting some numbers and look what will come out :]
Same here. And my code worked for me. o_O
