During my time at my old job, I was given the task of porting projects to Unity 5 to give the visuals a new lick of paint. This involved changing material properties, adding pbr textures where necessary, lightmapping using Unity 5's realtime GI, adding animated characters, and using Asset Store plugins for camera paths and image effects. Here are some renders!
NOTE: I do not own this IP nor was I involved in creating the initial assets for the projects. Only lighting and additional characters and camera effects.
