Hi all:

I'm working in the current IRTC stills topic and everything works fine till
now except for the media in this model.
I think fire looks realistic enough, except for that strange "yellow tail".

The clouds are four semitransparent planes (all with the hollow keyword).
I've tried another possible combinations (the Gilles' fastclouds.inc file
and the fastsky.inc file from Rune).

If I use the clouds (anyone of them) this yellow tail appears. If I do not
it doesn't appear.

Assumed Gamma is 1

The giraffe and the media container are bicubic patches (from hamapatch).
The scene is made in Moray (z is up) and rendered in the last pov candidate.

The material is as it follows:

#declare jirafa_fuego_txt =
   material  // jirafa_fuego_txt


      texture

          pigment
         {
            color rgbft <0.0, 0.0, 0.0, 1.0, 1.0>
         }
         finish

         }
      }
      scale  <0.2, 0.8, 0.8>
      rotate -20.0 * x
   }

Can someone help me with this?

Thanks in advance.
