Hey guys,
so I’m in the middle of developing an Android app using Unity 5.4, for now I’ve just implemented a script that allows to draw straight lines using LineRenderer.
So this is how my game looks in-editor (and in the program itself):
The material used in the LineRenderer isn’t in use anywhere when you’re building the scene, so the compiler strips it out. If you add an object which includes the material in the scene, it should be available again.
