When rendering in Cycles these will pop up every so often on this rig. In Eevee it looks fine. I went through the vertex groups to make sure there's no doubling up or anything like that. Has anyone encountered something like this when animating their rigs? Cycles Render Eevee Render

  • $\begingroup$ I guess that's caused by the motion blur. In any case, this should be reported to developer.blender.org to fix it. $\endgroup$

    $\begingroup$ But first check if there aren't any weird drivers. Because if a driver causes some weird location on subframes (which you can't see in the viewport or in EEVEE), then this motion blur is correct. $\endgroup$

  • $\begingroup$ Thanks for the help guys. Turning off motion blur did it. It's strange as I copied my key frames onto an earlier save of this rig and don't have the same blur problems. $\endgroup$

OK, so I figured it out. Apparently autosmooth in rigs doesn't work very well when animated with motion blur. Turned off motion blur and fixed my geometry w/ holding loops and everything is fine.
