Prepare scene for animation in Yafaray. How to?

Hi. I finish my architecture model which include many object interior and exterior. I am satisfied with all the renders, using photon mapping and a sunlight. Now I want to animate the camera movement at different place of the model. The problem is that when I render the animation it compute all the model for each frame. And it take too long. Did I to join all my model / put those which is not in the camera field on another layer / delete some item ? I don’t know what is the good solution. Please help.:frowning:
