Problems
I have had several minor problems with this project, but I want to talk about my biggest problem. That is, when I went to render an animation, all my lights decided that they want to be turned up and over exposing my scene starting with the second frame and continuing on to the rest of my frames. The first frame, however, renders just fine. I have not found the cause and/or the solution to this yet, but I will find a way around this.
With More Time...
This project was like riding a roller coaster. Once I got into modeling, I was on the rise until I was done modeling. Then I started texturing and could not understand it for a day, and then the next day, it just clicked. Next was look-dev and I hated moving the camera, then, in class, we're shown the "Place Camera Tool" and that somewhat helped. Finally, were at animating and other than my lights going crazy, I like my final render.
