Hi,
@
I remembered thread but couldnt find it anymore 
Concerning FlipBooks, please correct me if Im wrong here:
-
Since the frames are organized in rows and colums (without dimensions), it is implied that the flipbook frames are square shaped.
One cannot create a 16:9 flipboox texture (without letterboxing, the frame still occupies a square region in the texture). -
As the max texture size that UE4 can import is 4096x4096, a one second “film” (25 fps) can only be around 800x800 pixels in size.
Thus a 320x200 film (still occupying 320x320 per frame) would yield 144 frames, or 5,76 seconds, animation (per texture). -
Daisy chaining flipbooks together to create longer sequences is possible, but questionable in terms of resources/performance…
Is line of thought correct?
Cheers,
