Why is material disk size much smaller than the disk size of the textures that make up the material?

Hi. The reason i’m asking this ques is that when auditing the assets in my game (it’s for mobile), I noticed that even though the textures are around 1mb each in size, all the materials are only around 100k.

Because the game is for mobile i’m trying to make the game package file as small as possible, in terms of disk space. And so I was wondering if the textures are packaged in the final game file - or whether it is just the material?

Thanks.

Different asset types are normally not merged, means: one file for your material and another for you texture. You can actually unpack your .pak file to see what files are inside and also check what sizes they are.
Generally things like Resolution (obviously), compression and Mip maps are making the size of a Texture.

Hope that helps.
