Project : Unreal 4.12.5 - Paper2D project.
Skills : Not new to UE, but fairly new to Paper2D.
When I use TexturePack to create my spritesheet and accompanying texture file and I use for instance the PNG-32 (PNG-8 gives a similar result) texture format with whatever pixel format, I end up, at the TexturePack-side, with multiple texture files (2048 max size) and they are all around 4 MB each (around 1 MB for PNG-8). But after importing them into Unreal via a Paper Flipbook, the same texture files are generated in Unreal but are over 20Mb each … … so a couple of animations, one would expect to be max a couple of MB’s in texture files, end up near 100 MB !!! My customers will need super-devices with extreme large drives on to have a game (with very few animations) work like that …
Correction : these large uasset texture files are after packaging (cooking ?), see my next entry. The result however is the same. I end up with a game of 4 sprites each with an animation of about 30 secs and a packed pack of over 300 MB …
I looked at the settings for all UE files (like the texture files in UE), but did not find anything useful.
I played with the source texture file settings in TexturePack and I had the best results, but still unacceptable, for settings : PNG-32 with pixel format RGBA5551 (I need the alpha). There, I ended up with texture-files of 15 MB each in UE.
Looked on google and the forum, but did not find anything useful.
Any help would be appreciated.
