Why does Editor Log show such HUGE file sizes?

Unity Engine

I have a relatively simple game that ultimately builds a 240mb Mac Desktop file. I have gone through my game’s hierarchy, found each and every texture, and reduced it as much as I can without ruining the appearance, as per Unity’s document, “Reducing the File Size of the Build”.

I suspect that Unity is including ALL of my project’s assets in the build. The Editor Log below lists everything as “Used Assets and files from the Resources folder”, yet these are NOT in the Resources folder:

  • UsedAssetsand files from the Resources folder, sorted by uncompressed size:
  • 21.3 mb 11.3%Assets/Airliner777/Materials/airliner777_cockpit_nrm.tga
  • 21.3 mb 11.3%Assets/Airliner777/Materials/airliner777_cockpit.tga
  • 8.0 mb 4.2%Assets/KippWorks/Feb5/City-Ver1.fbx
  • 7.9 mb 4.2%Assets/Images/AM3d_Splash_1920X1080-PRO.psd
  • 7.9 mb 4.2%Assets/Images/instructions/instructions1.psd
  • 7.9 mb 4.2%Assets/Images/menuImage.psd
  • 5.5 mb 2.9%Assets/Audio/music/we-want-to-be-free.wav
  • 5.3 mb 2.8%Assets/world composer/sept29kipp/Jamaica-2048.png

See that first asset? The one that is 21.3mb? The raw image is a 2048x2048 16.0mb .tga file. Here is an image of my inspector, showing how much I’ve attempted to reduce it’s size. I’m not sure how to get the file sizes down. Please help.

Mip mapping.

An uncompressed ARGB image would have nearly identical size to its TGA source, except mip mapping increases the file size by roughly 33%.

What I see in the attached image above is “Format: Compressed”. Have I not correctly set this image for compression?

Hmm … didn’t notice that the format was set to compressed and max 512, and yet it is not compressed, nor is it reduced in size. Most likely you have an override in the platform specific tab your editor is currently set to be using. Click on the icon tabs next to default and see if any have “override” checked on.

Fixed, thank you! Now I must check my entire project for similar occurrences.
