Issue with shaders and WebGL
Hello,
I am having some issues with getting shaders to work in WebGL. I have the following shader code in Unity:
LineRenderer lineRend = point.AddComponent<LineRenderer> ();
lineRend.material = new Material(Shader.Find("Particles/Additive"));
This works fine in the Unity player (editor) with no errors. However, after building the project to WebGL and trying to use it in the webpage, I get the following error:
NullReferenceException
UnityEngine.Material.Internal_CreateWithShader (UnityEngine.Material mono, UnityEngine.Shader shader)
UnityEngine.Material..ctor (UnityEngine.Shader shader)
SceneShape.createTranslationGizmo ()
SceneShape.Start ()

I have taken out the shader code and the error dissappears. Does Unity WebGL support shaders?
This is not a WebGL problem. Your standalone app will write the same error in log file because Particles/Additive shader was not compiled in the build.
It happened because the shader was never referenced from anything in a scene. And to fix that you need to manually include this shader by going to Edit > Project Settings > Graphics and adding it into Always Include Shaders list.
