Hi there, here's my first post.

I am trying to create an animation where one follows a car on a mountain road, and as you progress on this road, some houses pops on the side of the road. The thing is, I've made an animation of one house popping out of the ground with the fences progressively surrounding the house and the grass coming out of the ground… but I don't know how to duplicate the whole animation multiple times.

I know how to duplicate an object with a particle SOP but if I do so, all the animations start at frame 0, I would like my animations to start at particle birth… but for this they shouldn't be keyframed on the main timeline. And I don't know how to do otherwise.

Sorry for my bad english, any hints are welcome !

something like this?
One option is using copy and timeshift sops. You have to play with the expression in timeshift sop or copy sop to get the desired value.

This is impressive ! I am still analysing every little chuncks of expression.
Very very instructive !
Thanks so much !

I learned this from the file posted on the odforce forum
