Ue4 fail to properly export texture.
The full error message is:
"TextureName": Texture is RGBA16 and cannot be represented at such high bit depth in .tga. Color will be scaled to RGBA8.
This ruins the normalmap making it pink. How to solve this ?

Hey guys, So I discovered a work around of sorts for this issue. When you export the texture, it gives you the warning but it still outputs a TGA file for you. If you open the file in Photoshop (or whatever image editor) you'll see that it looks wrong. What's happening (at least in my case) is that it has inverted the color channels. So Green is fine but Red and Blue were flipped. You can fix this easily enough by copy and pasting the channels to their correct spot in a new document. So the Red channel is actually the Blue and the Blue channel is actually the Red.
Here's a screenshot of my normal map that was exported. The left is how it looked when I opened it up after getting the warning message and the right is after I swapped the Red and Blue channels.

I think the only way to work around this to setup the source project for a migrate instead.
The export functionality is clearly lacking, but the migrate is just a one-to-one transfer from one project to another as long as everything is setup correctly with the folder structure.
Hope that helps!
