Hi everyone. I’m having trouble with an animated normal map. I have created a normal map video as a wmv file and imported that into UE4. I can use it in my material as a base colour with no problems but when I use it as a normal map it seems a little off. I have a fresnel effect in my material and when I attach the normal map the fresnel becomes lopsided, showing more on the right of the mesh than the left. Here’s how it looks, the fresnel is multiplied by a green colour and added to the emissive.
I have a feeling this is to do with the adjustments UE4 makes when it imports a normal map since it makes no adjustments to video files. Could someone tell me if I am correct and if so, how can I replicate these adjustments in after effects?
Thanks in advance
