DESCRIPTION:With the next generation of ground and space-based telescopes 
 (e.g. Herschel\, ALMA\, e-Merlin) bringing improved resolution to bear on 
 emergent planetary systems\, theory and simulation must keep pace to inter
 pret observations. We present a means of directly incorporating Monte Carl
 o Radiative Transfer (MCRT) techniques into Smoothed Particle Hydrodynamic
 s (SPH) density fields. This allows us to produce synthetic telescope imag
 es of these simulations\, and to determine the visibility of nonaxisymmetr
 ic features such as spiral arms and disc clumps. We demonstrate the techni
 que by considering the HL Tau system\, found by Greaves et al (2008) to ha
 ve a condensation of mass 15 Jupiter masses at ~65 AU (for which they prod
 uced an SPH simulation with similar features). We image the SPH simulation
  to determine the visibility of this clump by the next generation of sub-m
 m instruments.
