This should be added automatically. Is OpenGL enabled in the shader settings?

No, and it will never happen either, unfortunately. It's an enormous amount of work to do such a thing

It's pretty much the same procedure as seen in this tutorial, plus enabling light probes and lightmaps:

You won't, however, get as nice of an inspector window or the compile/feature branching, as it's tailor-made for that specific shader.

Strange, it should work in Unity 4

In Unity 5 or Unity 4?

No probs - you too!

Thanks for the detailed report anyhow!

This has already been fixed in the coming 1.03 version :)

Too late! It's already on the internet
