I use Unity's Sprite Packer, it's working great. However, when I looked at the build report (in the Editor.log) it turns out that the build often includes the generated atlas texture and its original textures too. It wastes too much space. I checked the size of the unzipped APK and the build report was correct. I tried several configurations (adding and removing textures) but I could not find any regularities.
Some observations: - I could reproduce this only if I use 25+ textures in an atlas with variable sizes. - Texture compression settings did not matter. Packer policy could modify the result but did not solve the problem.
Has anybody had similar experience? I can upload my test project if necessary.
