Rendering Selected object only with Network Rendering

[DHudson]

Hello! I am trying to render just one object in a scene to my networked computer. I select the object to render. In the Render Setup > Common tab drop down I choose Selected. In the V-ray tab under Image Sampler I choose Render Mask: Selected. I send it to Network rendering. It looks like rendering will begin on the networked computer but then I get the message "You must have valid objects selected." I look back at my scene and the object is still selected. Any idea what I am doing wrong?
Thank you for any help.

I usually put hem on a specific layer and render by using Render mask=Layers . Make sure you have in Settings/Prevoius render = clear

Thank you, Zoranm, that worked! The edges are pretty bit mapped. Is there a way to correct that?

Try increasing Min subdivs. Othervise, probably easier, fix it in post by way of blurring the alpha channel
