Paper2D spritesheet - extreme large sprite texture files in UE4 after importing via spritesheet

No ideas at all ? Looks like I’m the only one having this problem or is nobody using Paper2D and spritesheets (from TexturePack) ?

Since in UE the size of the texture file is acceptable, but after packaging, it is not, I suppose it has nothing to do with TexturePack, but is possibly some mistake in cooking ?

For a moment I thought I had found the answer, as for android, the cooking must be done for the diverse formats supported, but, as I mentioned before, the same problem must be for the Win32 & 64 as well as they have slightly smaller packs, but still at least 250 MB after packaging.

Have looked around so far to find something on it, but nothing so far …

Again, any help or insides are appreciated !

Cheers,

Geert
