Help with my stage

[marp]

well I am working on a stage that i cannot animate some things, I just can animate the models that are in "CHR" and I have 1950 frames in that, so my question is: How can I animate models in another "CHR" because i have tried put one more below the first one, but when I play the stage, the models don´t do any animation.  :(
So I accept any help or advice.  :af:
