Is Texture Sheet Animation not work for unity 5.6.1f1 ?

Hi, when I update unity version to 5.6.1f1 from 5.5. I found Texture Sheet Animation is not work in this version.
I don’t know why. 5.5 is ok. anyone can tell me how to fix it?

is there anyone to know??

Same problem here. Doesn’t work in 5.6.1f1
I’m using texture sheet animations inside a particle system.

Can you elaborate on the problem?Are you both upgrading? We have some known issues when upgrading some particle system properties if they are part of a prefab. We are still working on a fix at the moment.
