Rectangular Textures for compositing purposes

Unity Engine

Hi,
I’m trying to import a few rectangular (still power of two) textures that aren’t meant to be rendered but instead are pieces that will be composited into a larger square texture (think clothing textures in a character customization system).
I have a series of 256x128 textures that I’ve imported into Unity. While they remain 256x128 on disk, the corresponding Texture2D resources report them being 256x256.

I know this probably is done automatically because I’m in a iOS project. Is there any way to prevent that?

Thanks,
Jeff

If you use PVRTC texture compression, it will convert them to square. You can just override texture settings for those textures
