Objects disappars when zooming in in Cinema 4D?

Hi! I position and model Minecraft characters in Cinema 4D as a hobby, and when there was nothing else loaded in the animation but only the character, I can zoom in very close to the character's face and see the face expressions. But when I tried importing a world, and when I loaded the rig and tried to zoom in on the face, the character disappears from my screen. I tried to move the world and character to different positions and even tried moving the character way over the world, it still has the same problem. Can anyone help? This is my Geography coursework!
