Hello,

I find **polyhaven.com** site for HRDI images.
I try to test this image :
<https://polyhaven.com/a/kloppenheim_06>

SDL code :
...
sky_sphere {
  pigment {
    image_map {
      exr "kloppenheim_06_4k.exr"
      map_type 0
      once
      interpolate 3
      }
    }
  }
...

The "exr" format is well recognized with syntax highlighting.
"Apercu" open the file with no issue, but POVray say :

Possible Parse Error: Cannot initialize semaphore (Function not
implemented).
Fatal error in parser: Cannot access data in file.


Not yet implemented or bug with v3.8.0-alpha.10013324.unoficial ?

I tried to get the image, but it "arrives" as:
  $ file kloppenheim_06.exr
  kloppenheim_06.exr: RIFF (little-endian) data, Web/P image, VP8 encoding,
1560x780, Scaling: [none]x[none], YUV color, decoders should clamp

and POV-Ray doesn't know that format.  can you post an example image here,
please?  (want to try with beta.2)


regards, jr.

anyway, using a different .exr image, your code works on the beta.2, scene code
below.  fwiw, I think clipka rolled back the alphas to 9945627 to make the
beta(s).


regards, jr.



#version 3.8;

global_settings {assumed_gamma 1}

camera {
  location <0,0,-5>
  right x * (4/3)
  up y
  look_at <0,0,0>
}

sky_sphere {
  pigment {
    image_map {
      exr "blurSmall.exr"
      map_type 0
      once
      interpolate 3
      }
    }
  }

did a quick test with 9945627, works ok.  (proviso: I compile from source, and
get the archive(s) from <https://github.com/POV-Ray/povray/tags/>)

Check https://povrayunofficial.wordpress.com

The old site is no longer updated because I can not contact the owner 
of that domain and I lost access.
