  1. I Bring in the hdri just as you did but mine acts like I am zoomed way way way in like I can only see 1" of a cloud. I move the view around and the sky goes away to black. All the other hdri that I bring in its the same. NI am using the VHDRI_Cloudy04_HyperfocalDesign.exr image. I am doing something wrong. I tried to set my scale to metric but no diff

  2. Its a shame cycles doesnt have a ray switcher like Mental ray. they overcame this problem by using 2 maps. 1 blurred for lighting and 1 unblurred for reflection rays. although that said i dont know if cycles distinguishes the 2 ray types (being my physically modelled)

  3. You have fireflies because you didn't adjust the Clamp value. Set it to 0.95 and that will clear them up. It's under the sample settings.

    Also, the fireflies are not related to HDR lighting, they're related to the physical renderer. They occur on any kind of lighting (HDR, point, spot, etc).
