I have created free playmaker actions for xweapon trails. You can download them from my github account here:
https://github.com/dumbgamedev/XWeaponTrail_PlaymakerThe Xweapon Trails asset is about 8$ now on the asset store. It creates nice smooth weapon trails after swinging your weapons around (can be 3d, 2d or VR). You can add trails to add kinds of objects (doesnt need to be weapons). Anything you want a swoosh movement after. I choose this one because it has a 5 star rating and tons of buys.
https://www.assetstore.unity3d.com/en/#!/content/20972I created a tutorial how to set it up in VR and use my actions (however the same principle applies for 3d or 2d).
