I'm making a map and my textures are RGBA32. If I open them in the inspector, there's no option under the format dropdown to change them to DXT1 or DXT5. Is there a solution to this??
It is a PNG file and it is set to default. It's a really small file(16x16) that gets used as a color reference. A red car would use a couple red pixels for the whole body of the car, for example. It looks fine in the scene. Heres a screenshot of the editor:
Yeah, PNG sometimes can use a different color format besides standard RGBA (ex. Indexed colors), which might not be supported by compression algorithm. But glad you found a solution.
