    I am trying to create an HDRi Planar Background example today, and it is not working properly.

    Let me see if we have a problem.

    Hi Al

    Can we import HDR files direct into background yet?- I keep trying\testing with no result - Is there a definitive tutorial for HDR backgrounds/ I just cannot get any image to work consistantly and on the few occasions I do get background to convert HDR\work the minute variation in tone in image editor is a completely useless.

    Half the time the backgrounds do not appear in renderer - really do not know what I am doing wrong

    Any help gratefully received

    The Planar HDRi can be used to brighten or darken the background using Lighting Channels.

     

    Because it is an HDRi image, and not just a normal image, when you darken it, it will not darken uniformly (as it would it a paint program). Instead, the lighter places - which are expected to be lights - will darken more slowly.

     

    I am working on a sample image showing how to adjust the Lighting Channels for an evening sky for the other thread: http://irendernxt.com/forum/topics/evening-sky

     

    I will post an example there when it is done.

    ok, so why to convert it to HDRi?
  • Render Plus March 17, 2011 at 7:09am

    You can use an HDRi sky for light , with a different background.

     

    An HDRi Planar background is not used for light or reflection.

  • Alain Bonnefoy March 17, 2011 at 7:07am

    So when the background image is set to "visible", do we see the HDRi image or the background?

    Is it possible to use HDRi image for light only and the background as visible landscape?

    It can be used as an KDRi Planar background, or as an HDRi sky.

     

    However, the images itself may need to be different. An HDRi sky is assumed to be a complete 360 panorama. It can beused for visible sky, lighting and reflectios.

     

    An HDRi Planar Background is assumed to be a flat image. It is not used for lighting or reflections. One of its values is that it works better than just a background image, and that you can adjust its intensity using Lighting Channels.
