Dome Light "Lock to Dome Orientation" not working for me

[JezUK]

Typical scenario;

Exterior scene, Dome Light (at Origin), HDRI assigned to Dome's texture slot.

HDRI also assigned as Instance to Environment Map Slot and Environment is visible in Camera Viewport Background.

I rotate the Dome light but the HDRI doesn't rotate in the Viewport Background ???

"Lock to Dome Orientation" is checked.

Any ideas ?

(latest NVidia Drivers etc, VRay 3.20.03, Viewport isn't Disabled etc etc).

Many thanks.

Forgot to Wire Parameter the Dome light with the Horizontal Rotation - but shouldn't the "Lock to Dome Orientation" checkbox, which I've only just noticed, take care of that ?

it's only going to rotate the HDRI/DOME and not the one in your environment.

you have to rotate the map not the light

Well, if the dome is locked you can rotate the light, however, a instance in the Environment isn't going to rotate, too.

you have to rotate the map not the light
