    Keep in mind that rendering selected objects is never going to be technically correct, as you will be comping it on top of an existing copy of the object. So the edges will get more dense. Ideally you render the separate elements separately such that they can be comped over in post. Then it's OK to replace the "layer."

    It's like a colorist trying to color already comped footage by using masks. It will never be correct. It may look acceptable, but it is not the technically correct way to do things, as it produces incorrect edges. It leads to fake looking comps with bad edges, and even though it's the colorist messing it up the VFX artists get blamed

      Thanks, but I have several different scenarios where rendering selected object are perfectly technically correct.

          I am interested in hearing more? Do you have them on alpha and then comp them over a clean BG? In that case, sure.

          My point is that if you have your plants rendered already on top of some background all in one image, and then you select them and render them with a render mask-- then when you comp them over an already combined image you will get double edges, which is not correct. Of course if you break stuff into layers then it works fine. We do that with scene states, though, rather than render masks.
