In this shader tutorial, I show how to convert a reflection vector into UV coordinates for looking up a latitude longitude formatted texture in Unreal and Unity. This is useful for using a LatLong texture to make reflections. I also show how to do the math with 13 fewer instructions than Unreal's built-in LongLatToUV node.
