How to move hdri after posing a scene?

DefaultName

Hi there. I want to use a hdri for my next scene, but I don't want to move the figures or camera. 

What I'm currently doing is previewing in Iray and trying to rotate the dome or move it along the xyz axis. But this is way too slow and resource intensive, even for low res equivalents. Am I doing something wrong? Is there a quicker or better way I can position the hdri without moving the scene? Thank you.

I don't understand how rotating the dome is resource intensive, other than having to re-render. Even that shouldn't be bad since it doesn't take long to see enough to decide if the lighting and background are sufficient.

One thing that I do when I'm rotating HDRIs is to enter the rotation directly instead of using the slider.

1. I reset the rotation to zero (if it isn't already)
2. Then I enter the rotation directly in the box to 60, 120, 180, 240, etc.
3. If I feel like I went too far, then I go back by 30s ... 240, 210, 180
4. Depending on how much detail in in the HDRI, I might to back again by 10s ... 180, 190, 200, 210
5. Once I'm close, then I might use the slider for fine adjustments

This seems to cut down on the number of redraws / rerenders that the system has to do and feels less frustrating to me.

Thanks JohnnyRay, I forget that I can do that for some reason, but that is a good idea.

I understand what you mean Fastbike, and I didn't mention that this was a fairly complicated scene. With all the props in it, I'm starting to realize an hdri just might not suit, as it won't really matter anyway, seeing how most of it would be covered up.

Remember that you can set Draw Dome to off and get the benefit of the lighting without the background intruding. You will generally get even lighting so that you can use spots to foucs on specific portions of the scene.

If the background isn't important, you can also use Sun-Sky which should enable you to get more precise control of your shadows.

Great advice! I'll keep it in mind!
