[SOLVED]Confused about texture compressed size!!

Graphics Shaders & Materials
1

I am using Unity 2.5, Mac OS 10.5.8
I have created the smallest test scene with:

  • mainCamera
  • testTexture
  • and a C# script

Texture size in Finder: testTexture.tga = 412KB
Texture size in Inspector Preview: 512x256 RGB DXT1= 64.0 KB

Build Size in Finder(testScene.unity3d) = 28KB
build Size of an Empty scene (no script, no texture) = 8KB

What´s the size of the texture compressed: 20KB?
I thought it was 64KB!!!

This might be a silly question but I haven’t found any answer while browsing the forum!

Thanx for any help!!

Web builds use LZMA compression, as you can see when making one. Since DXT uses lossy compression to a fixed size, this can often be further compressed losslessly, depending on the texture. The compressed size in the editor refers only to how much RAM the texture uses, not disk space.
