Animate arrow in a 3D space
on Aug 30, 2018 at 1:58:57 pm

Hi all,

thank you in advance for any help you can give me about this project. I need to create some arrows flowing inside the ventilation system ( see the attached video). The camera is moving, so i would like the arrows to follow the movement in the scene. I've already tracked the camera, but after that? Thank u again for any help.

There's no attachment.

For a few arrows and no actual geometry (2.5D) I'd just drawn the paths(using position keyframes) and auto-orient the arrow heads (or rotate them manually, since auto-orient gets crazy sometimes).
If you need trails with more than 2 dimensions, you'll require an external plugin (any third party particle plugin can generate a trail).

For the best result I'd export the position+camera data to C4D and go from there. (this requires a lot of experience and workflow knowhow, but its pretty straightfoward and effortless once you know it)
