First of all, when you add the metahuman into the sequencer, in the animation (for this exemple the body) the sequencer choose the defaultslot →
If i check the other metahuman that i added we have defaultslot1 →
As you can see, the sequencer use different slot… Here my setting for each metahuman on body animation :
Now, for each MH you need too add the right default slot before the output pose so that the sequencer can animate you MH →
Well i could change the name but i used default value ! Here how to add a slot →
When you click on it you can add the slot name that you want (must be the same as the sequencer) →
Note : You can only use defaultslot on both as long as in the sequencer you change defaultslot1 to defaultslot.
Now you don t need to use custom mode on the animation track and wont be trouble with the first frame A pose.
Just hoping it help someone !!!
Thanks,
