These are the normal maps I'm getting from NinjaRipper. If you switch the image channels you can definitely see there is normal information going on there, but it's not the usual switch/invert channels to get them right.
This normal map is only the R and G channels, known as the normal maps X and Y.
Normal maps usually ahve 3 channels, RGB right, but the B channel is usually useless information and so can be discarded and rebuild in a shader in the engine itself.
That frees up space to use the B channel for something else, such as a height map, or a roughness map.
Looking at this particular texture, the B channel is entirely diffrent to the previous 2, and its a lot lower detail,it could be a roughness map, I can't really tell sorry.
It is also dumping this:
Does anyone know what is going on there?
I could not figure this one out.
Thats an LUT texture, LookupTexture.
Typically thats applied to the camera as a post process.
These files handle things like color tinting, you take a screenshot of your scene, with no color tinting applied, take it into photoshop, along with a clean version of an LUT texture, and then in photoshop you start applying effects to the above layers, such as darkening, color tints and so on.
Theres a more detailed explanation of them and what they do here

I don't know what engine the files you've exported are from, as a few engines use LUT textures.
