No DOF on particles or replicators. Seems a big shame to me.

What would at least be a cool workaround is being able to turn replicators into real individual objects so you could design a shape based on replicators, then turn all replicator elements into individual objects (within a group) and then they would respond to DOF.

HANG ON!! I'm just playing around with a replicator in box mode in 3D and it DOES seem to be responding to DOF.

ODD because in the manual it states:

"Certain complex objects will not be affected by depth of field settings. These objects include local 3D text, paint, particles and replicators. The objects in these groups will likely be spread out along the z axis, but the camera cannot measure their relative depth and thus cannot accurately render depth of field. The entire object will be rendered with a constant level of blur."

There certainly does seem to be a variety of blur dependent on how close to the camera the individual particles are, and as you say it looks pretty darn good. Seems to render pretty quickly too.
