I don't know what I've done wrong, but it's the first time that this is happening to me. I made an animation with different color falling solids and when I render it, everything is white. Here is my file so you can look it up maybe. PS: I know it may have something t do with texture/material but I am too much of a noob to solve my problem.
What gets rendered is the camera view.
Your camera is aimed to a place where there are no objects.
