Unreadable texture

Message

Unreadable texture.

Explanation

Sometimes some of the assets (textures included) get damaged for various reasons: artsis' errors, broken merges, file system or software failures. Whenever Luna attempts to export a texture and is unable to get its pixel data, it will report this message to Luna expert.

Can it be simply "Read/Write" disabled?
Not really. Luna is using multiple techniques to gather texture data, starting by making a copy of the underlying texture source file in case it is PNG, up to utilizing Unity's Graphics API to copy pixel data to work around compressed formats. Thus, if Luna fails to extract pixel data from a texture, it is most likely damaged in one way or another.

Severity

Medium / High

Steps to fix

Fix the underlying asset.
