My scene contains transparent objects that pass through each other during the animation but it seems to be casting a shadow when the overlap

I've attached a screenshot if anyone can help.

    $\begingroup$ Although that isn't exactly related, do not plug output from Normal Map node into Displacement input socket of Output node; use Normal input socket of Diffuse node instead. See blender.stackexchange.com/questions/16443/… $\endgroup$ – Mr Zak Apr 22 '16 at 12:17
  • $\begingroup$ you can always just turn off cast shadow in the object menu, and animate that too $\endgroup$ – Allofyoush Apr 22 '16 at 12:49

    $\begingroup$ that looks to me like overlapping geometry and errors produced by Z-fighting, but without access to the file is hard to tell what the issue is. $\endgroup$ – user1853 Aug 21 '16 at 6:23
  • $\begingroup$ are you sure this is caused by the transparent objects? does the artifact disappear when you hide them on a layer which is not being rendered? $\endgroup$ – aliasguru Aug 21 '16 at 17:17

    $\begingroup$ That's z-fighting, not a shadow. You have some overlapping geometry there. $\endgroup$ – PGmath Sep 20 '16 at 13:55
