Keeping filezise small on exported packages by leaving out metadata possible ?

Unity Engine
1

I noticed that Unity includes reworked textures (from metadata) into my exported packages.
Except when i use DDS textures, but DDS textures have a problem with displaying correctly when i use linear color space.

I also know that i can set the resolution of the textures very low to keep the metadata filesize low and thus keep the size of the exported package low, but i rather don’t want to put my 2048px texturepack on the asset store with 256px texturesettings to keep the filesize of the exported pack low, cause then everybody that buys my asset needs to set the texturesize back to 2048px before they can use it as intended.

is there a way to export the package with only the settings, and no included re-rendered double texture (metadata) ?
cause if i have 1 PSD texture and the filezise is 1,5mb and my settings are 2048px for that texture in Unity compressed as DXT1, then Unity keeps my 1,5mb file + a 2,7mb re-render as metadata and includes this in my package, this makes my package file huge and the guys from the store just refuse to put my pack on the store because of the filesize, it happened once so i want to keep it small this time but still convenient for users, just the PSD files and settings, no more.

Anyone knows how to accomplish this ?

Have you seen that in the actual packages created by the asset store tools? It may contain export with different options than you get exporting manually from the editor.

That is a good one, i did not see that cause i can’t get my packages from the store.
If you want to see the package uploaded to the store you have to buy your own asset first.
Cause authors of assets cannot download their own asset from the store.

So maybe you are right and those packages could be different, can anyone confirm that ?

Actually, when you run the Asset Store Tools you’ll see that it creates a temp package before uploading it. You should see that in a window that pops up. If you wait for the export to finish then check the size of that package, you should be g2g.

cool, i’ll check that out, thanks for the tip !
