Have you ever experienced such an issue? Driver not updating when rendering animation, but updating when single images are being rendered one by one?


Case description: I created empty, linked to a motion tracker. Then I parented a plane to this empty and baked action of this plane. Next I created driver for x offset of a Strip in Video Sequence Editor (Image of the setup below). Strip, which the driver is for, is moving nicely in the viewer and the Backdrop of the VSE, but when I try to render the animation (both to mp4 and PNG sequence) it doesn't. What's more interesting, it is rendering fine when I try to render it frame by frame with F12. Any Ideas? Is it a bug or I just forgot to turn something on?enter image description here

  • $\begingroup$ No I haven't. Usually I'm animating offset with F-Curves, but this time I need it to stick to the motion tracker. I'm not searching for alternative solution for the offset animation cause it's only dozen frames and I already rendered them. I just want to know if this driver behaviour is normal and I just didn't switch something or it's a bug and I should report it. $\endgroup$

  • $\begingroup$ I don't have much experience with the motion tracking side of things but it does seem like a bug, so go ahead and report it. Check this out. $\endgroup$

  • $\begingroup$ Same problem here... How did you resolve? $\endgroup$ Commented Mar 26, 2022 at 0:39
  • $\begingroup$ I didn't @BonecoSinforoso Just rendered everything frame by frame with F12. $\endgroup$
