Scale of Sky MXI?

I feel dumb asking this, but I have had this problem forever using studio, now I am having it in cinema. I looked everywhere before asking so any help on this would be huge. Is there a way to make my sky hdri/mxi scale down so that it seems farther away without having it tile? Many of the hdri's convertet to mxi are way too big as backgrounds when I try to use them to illuminate my scene. I must be missing something really simple. Does the size of my original image have anything to do with it? Anyone?

Hi Eric,

Any spherical panorama is virtually at infinite distance. You should avoid any kind of tiling and your map aspect should be 2:1. In this case, your map looks correct and it's a full spherical environment map.

Regarding the size illusion, you need to set a proper focal length for your camera. You can easily preview this in realtime by following the steps below.

1-Open your scene in Studio.
2-Load your HDR as environment in all channels (even only bkg is enough).
3-Set viewport to camera view.
4-Press "K" in viewport and preview your environment.
5-Adjust camera focal length.

Best regards,
tom

Yikes. If I took the camera focal down to 10 it started to look normal. Still when I aligned my scene floor plane with the floor plane in the HDRI the hdri was too big and not to scale with the object in my scene. Maybe I need to find myself some hdri's that are not taken with such an extreme focal length if this is the problem.
