Multiple animations and State machines

So, I’m trying to create a state that will play multiple animations upon starting the scene. However, i can only make one animation per state. is there anyway to have multiple states play upon starting or can I attach multiple animations to a single state?

Do you mean multiple animations - one after the other, or do you mean 1 animation on the arms, one animation on the legs, one animation on the head - all playing at the same time?

Also - have you looked into blend trees?

Also have you researched animation layers?
