Hello, I am working on a large UE4 project with many characters and environments.
I am standardizing everything and currently I am stuck trying to figure out what to name my textures.
These are my options right now:

Is one letter too simple? Or due to the engines character limit, would it be wiser to use?
Would one letter be too confusing, or cause problems when searching for files on perforce or in unreal?
I don’t have a personal strong opinion on this, but am wondering what the conventional methods are.
Any thoughts are appreciated. Thank you!
