A simple question

I have experimented with Unity 3 but I always have problem with terrains lightmap. my portatil dont show shadows.I have Unity Pro but I dont know if is a graphic card problem. I active shadows, colliders and nothing.

Lightmapping with beast requires you to mark all objects that are relevant for the calculation as "static". See this tutorial video on lightmapping in Unity and listen carefully ;)

In general all not moving objects should be marked as static to signal unity it will never move. Unity can optimise the rendering by "batching" them together.
