Imported an Alembic animation to Blender. How can i time-reverse it? I imported an Alembic animation to Blender from the VR animation app Tvori. How can i time-reverse it? i need it to play as intended but then would like it to play backward, so to create a loop. and then render. is it even possible?
i'm a total beginner so i don't know anything about how the Blender timeline works, but coming from video editing it's hard for me to look at the timeline and not even see a clip on it that represent my "animation" and on which i can maybe right click and change settings? 
i know, i sound very ignorant about all of this which i am.

thank you for any response!

looping alembic
start alembic at specific frame

(e.g.) My alembic animation has a length of 240 frames.

Select all the objects, which were created on alembic import and go to the constraints or modifiers [properties tab].
Hold ⎇ Alt and  LMB click Override Frame.
Then ⎇ Alt LMB into the Frame field and type # 240 - frame.

A driver will be created for the Frame field and the field will turn purple.
Holding the ⎇ Alt key ensures, that this happens in all the modifiers and constraints of all the selected objects. You can confirm this, by individually selecting the other objects and double-check that their Frame field of the Cache Modifier and Cache Constraint is also purple.
