A juicy problem.

  Onyx 2, 3 pipe, 10 processor, IRIX 6.5.3,
  same problem was on IRIX 6.4.

  In a performer app, on a 3 pipe IR system
  I have a number of objects moving through
  the scene which disappear when they pass
  pipe (and sometime channel) boundries on
  screen.

  I have noticed that there is sometimes a
  static copy of the object visible on a
  different pipe to the moving object.
  But there is only one set of the object's
  geometry in the scene.

  I use pfDCSTrans and pfDCSRot to modify
  a DCS which is above the appropriate
  object's geometry in the scene.

  I guess this is a multi processor
  problem, but I don't know where to start
  looking for the problem.

  Can anyone help please.

  Cheers,
  Gary.
