No it is not the case, it works really perfect, b/c the old hdr was created not from many exposes, I use Artizen that have special feature with **HDR tone mapping** for hdr images to correct everything . The HDR images from poser was above the 0.0 value that why the sky looking so unatural blue and the other areas create to much shadows.. making the correction I got back to 0.0 . Poser have the **Intensity** : Luminosity  and the **Contrast** : Midtones   only .. here is what I can correct with if is wrong or looks unatural..to bring back to right value. Many pple import the images for the hdr as 2.2 display curve , digtal cameras use 1.0 ... on other aplication as max you can set the display curve to 1.0 but not in poser that why the render looks to dark and over exposed with light too...
