Hi all.
Been struggling with this for hours now. I am trying to animate the Follow Path Offset of multiple objects. Let say 3 objects as a test.
By creating an active key I have managed to animate just 2 of the objects but no luck with the 3rd.
There MUST be a way to select multiple objects and animate tham all at once. I know you can with Location,Rotation etc but This is Follow Path Offset.
You can’t seem to just use the ALT key when Keyframing as you would normally.
Thanks in advance.
You could use a driver. Offset-field RMB copy as driver on the first one. RMB on the second - paste driver and then edit driver - add or subtract value e.g. 5. Repeat for third
What is this ?
You should be able to select all three objects and see all their respective keyframes in the graph editor.
When animating the Follow Path Offset I can use ALT and increase the offset of multiple objects at the same time, but you can only insert a keyframe for 1 object at a time.
I want to animate as an example 3 objects at once along the path via the Offset.
Just create one keyframe for each and do the rest in the graph editor
Yeah, but I was using that as an example. In the final file I’ll have maybe 100 objects moving along the curve. I’m just trying to see as a test f I can get it working on 3 objects easily.
Thanks for the reply.
Mabe in the graph editor ? If you select all of them in the graph editor and press i there ?
Yeah it works. I just selected 2 paths and in the grapheditor evaluation time and pressed i over the graoh editor - selected channels. Then you haveto adjust the value afterwards, but thats not too bad
Not sure what you mean.
Attached is a test file, but imaging you have 1000’s cubes.
How did you animate the offset for all 3 cubes in 1 go to get them to the end of the curve as an example.
Thanks

yeah bugger. I had a separate path for each object. then you can select all the paths and it works. but i dont know how to set that up with a 1000 objects. i see that you want one path. i tried link animation data, but then you have the same animation for all objects and you cant change it individually. really no idea. scripting, but i cant do that. maybe geonodes. you could certainly use a collection and put all the objects in a animate them on a curve. hm
Got how to animate them all, but dont know how to space them out.
Thanks for your help. Can’t believe it’s not an easy thing to do. Oooh well. Cheers.
Cool. I’ll take a look. On phone not computer at the moment.
I am USELESS at GeoNodes at the moment. 100% useless
Cheers
Just plug an index node into the factor for where they are on the curve. Each item in the collection has an incremental index, so that should do exactly what you need
I qtried something like this earlier to generate the objects on the curve. Struggled with that and the rotation and positioning was all over the shop.
Will take another look.
Cheers
Try turning the Reset Children checkbox on
Think I did. But will give it another go.
Probably all good practice.
Cheers
Well I did it, not in an ideal way.
Ideally would have like to have used GEO nodes to create all the cars and offset them automatically and then being able to just animage the offset for all the cars at once.
Added the cars manually, didn’t take long and cheated and fudged the animate path and frames to get all the cars moving with just one click.
Thanks for all the replies and help. GeoNodes another day.
Result
How did you achieve the one click then ?
I tried the index thing with geonodes. didn’t really work. Would be nice to figure that one out.
Yeah, would have been nice to do it a bit more professionally/geonodes.
Once you animate the curve path (using animate curve button) and do a bit of fudging because of the speed the cars moved. That was it, just spacebar and they move along the path.
