No worries

The line "technique fallback { pass one { } }" is usually the very last fallback. It basically renders the entity as if no shader was ever applied, and is to make sure that no matter what hardware the user has they'll at least be able to see the entities. No states need be mentioned because the engine automatically sets those based on the entity's flags (such as TRANSLUCENT, BRIGHT, OVERLAY, and so on).

I hope that makes sense.
