What I wonder is why not just check box in render layer tab to enable/disable freestyle in particles?. I guess some technical impossibility of achieving this feature?
I can not find a way to avoid/exclude freestyle particles (objects, not hair) in Cycles. I have tryed putting the involved particles objects in a group, and then selecting the group as “Exclusive”. But anyway Blender continues to fill my 16GB of RAM and 16GB of swap… I have to kill Blender. Maybe I’m misunderstanding what Exclusive means, it says: “Select feature edges not belonging to any object in the group”.
Is there any easy way to do it without having to render more than one layer and composite?
