Hi,

   I wrote a simple scene for a heightfield that works in Povray but
when run in MLPov, has a problem opening the .hdr file. The sample
MLPov scenes work so I know both installations are correct and
working together.
   Any ideas?

Silly question: you got the hdr file in the same folder as your scene?
I personally put all the probes I got into the include folder.

Hi Jonathan,


   Not so silly a question. Thanks for the tip.

                                Jim,
                               Happy holidays.
