Hi
@ispinox ! I think the problem is "play next in", this value means "in how much time should the next animation play", if you set it to "0 seconds" it means "don't play the next one" (it would also be logical to say that zero means just play the next one immediately I guess but 0 seconds is treated as "no value" here). I imagine you didn't _mean_ to set this to zero?
Also, there's a toggle called "master", you can use that to only have one atom having the sequencing, atoms with the master toggle set to on will send a message to all other atoms and any other atoms with same-name animation will trigger.
