here are settings (MegaPOV) for below image
has anybody idea how to improve speed and look of it ?
the object is box for plantation of sprout (I hope it is proper word)
it is made of transparent plastic - I think that it could get settings from
transparent LEGO bricks but I can't find any - I think current version is rather
ghost instead of plastic :-(
the setting are inspired by sample files and some posts

global_setting{
  radiosity{recursion_limit 5 brightness 1.2 normal on}
  max_intersections 255
  max_trace_level 255
  photons{count 20000 gather 20,100 autostop 0}
}

object{
  Platform() // returns CSG
  texture{
    pigment{color rgb 1 transmit .95 }
    finish{
      ambient -0.3
      diffuse 0.8
      specular 0.1
      roughness 0.1
      metallic
      brilliance 1
      reflection_type 1
      reflection_min 0.0
      reflection_max 1.0
      conserve_energy
    }
  }
  photons {target 1.0 reflection on }
}
