If I make a blank project with a lanscape
like the open world template
and pkg it
I get a build size of about 300 megs.
I have projects with 20 gigs of assets in the project
but when I build just a single map from the proj that only has about 100 assets
I get less than 500 meg
That texture map could be in “plugins” or engine content.
IDK
only have the platforms you are building for selected, there is a setting to make sure engine content is copied, and you might want to enable the water/landmass plugins in the second proj before export.
seems strange tho.
