I am using the free version of Unity 5.6.1f1, and I know this used to be an issue long ago, but is it still in there? After I have baked my lightmaps, my normal maps disappear. See image below (spot the difference). I model and set up my uvs in Max. Painstakingly create beautiful maps in Substance. Then I set up my materials in Unity, for it to be wiped out at lighting time. Seems odd. Can anybody tell me why this happens and if there is a fix for it? Really appreciate it.
