I am not the first that makes animation with moving objects.So many of You have reached amazing results… But i still have a couple of questions…
I am following this tutorial and everything is fine till to the flickering at the reflections.
well you cant really render moving objects in flythrough mode. Thats a specific mode for static scene/moving camera. You would need to explore irradience map for animation mode to get flicker free gi in your scene.
you need to calculate the lc with irradience map animation mode. After when the calculation is done for the whole animation range, you can simply turn off seconadry boucne engine and just source the irradience frames. They will have the secondary bounce stored in them and will interpolate them correctly for the moving objects.
