The project does not load.

I tried to load the project and it got the following error:

Assets/Voxelmetric/Code/Shaders/UnityVC/Editor/StandardShaderVCGUI.cs(6,40): error CS0246: The type or namespace name `ShaderGUI' could not be found. Are you missing a using directive or an assembly reference?

I deleted the class StandardShaderVCGUI.cs but i can't play the project it doesn't start.

What version of Unity is this?

[AlesKriz]

Unity 4.6.5f

I'm on version 5.3.1f1 and can't replicate this issue. ShaderGUI is a unity class so I suspect it's from a later unity version. All the shaders in Shaders/UnityVC are variations of unity 5 shaders with vertex colors so they are likely not to work. You may need to delete that folder and use the custom/vertex colored diffuse shader instead.
