Our assignment required us to produce a seamless CGI video, where we took real-life footage and tracked it in Nuke, which was later converted into an fbx and taken to Maya for referencing our 3D objects. I've used the free zombie model from mixamo and purchased house and tree from Free3D. My initial idea revolved around adding emissions, but due to time constraint and technical issues, I removed it. 
I've attached a report below that gives a detailed insight about the project.
