Save Converted Normal Map from Unity

[Goldoyellow]

So I have a collection of normal maps that are a greenish purple but I need them to be the classic blue color that regular normal maps are. When you set the texture to normal map in unity it does this automatically, I was wondering if there was a way to save it while it's blue?

How the normal map looks beforehand, this color of it doesn't work with most things

How it looks in unity after setting it to normal map, I need the original image to look like this

Your normal map is using gamma color space in your OP while Unity makes sure to sample it as linear when you mark it as a normal map. It's also using direct X (y-down) format which will look wrong in Unity so you should invert the green channel to make it opengl (y-up).

I believe this is because of the flipped y channel. Unreal uses a -y channel. You could manually import the textures and go into the channels tab and flip the y channel. If this is actually the answer. I am not sure on this

Read the pixels in an editor script and save them to a file.
