In class, I discuss personal projects with my classmates. We watched the last graduation work together. See examples of real photography as a background. We think the effect is very good, and it also used the knowledge of 3DE Tracking that Dom taught us last semester.
The example:

Then I thought of the scene where I needed to use the bed in the dormitory, and I needed to build a soft cloth model. If I can use real shooting instead of traditional scene modelling, part of the workload will be reduced, and the visual effect is good.
I asked my teacher for advice and he thought it would work. And basically told me how to do this in Maya and AE. But I still want to try 3DE.
