Camera tracking problem from after effects

I exported camera tracking from after effects to cinema 4D, and I imported the camera tracking to Unreal engine using datasmith plugin. It was success, but I want the camera to close to ground, but when I try to close to ground, camera tracking doesn’t match. How can I make the character (hair clip) to be smaller so that I can make the camera to be closed to ground. Everything (tree and lake) are small. I want to make the hairclip to be smaller and make tree and lake bigger.
