Hello, does anybody know why iclone won't let me use the gizmo to rotate lights? For the longest time I thought it was simply impossible, and very tediously used the dials instead. But then this afternoon I tried it again and it worked!

But now it won't again.

Did I imagine that it ever did? Can anybody tell me what I'm doing wrong?

Make sure the light object is set to visible in the Scene Manager.

No you did not imagine it. You possibly clicked Rotate IBL at some point. But never clicked it again to set IBL rotation OFF.
So when you think you are rotating a Directional Light and it is not moving, you are actually rotating IBL. A little weird. But that how it works.
You have to click out Rotate IBL to be able to rotate Directional light.


Edit: yes, that is if it's visible as Animagic suggested

OK, thanks. I'll try that.

Duh! I think my problem was that I was LEFT clicking instead of right, and that's why I never got the Transform options that bring the gizmo up. Anyway it works now and I'll save your suggestions.
