Hello all I'm having some issues when opening normal maps - Basically the entire thing will be a mess of colours and I'm unable to use it. I'm usin​g Photoshop CC 2014 for my editing needs, with the Nvidia Normal Map kit installed, this is basically the first time in my retexture history I've come across this sort of issue. It looks like a piece of pixel art, very dense and just fluttered with colour. So I was wondering if anyone had the same issue and possibly had come up with a solution?​
