I've had an environment project going for a long time now and am intent on finishing it up quickly, so to easily keep track of my progress and perhaps getting some good input from people here I will do my best to update regularly.
The thing I'm focusing on improving right now is material and lighting (including learning about baked vs non-baked lighting and UE4 in general.)
The environment is meant to be the first scene in an adventure game that would be urban-fantasy inspired by stuff like Narnia or The Longest Journey. The main character would start out looking through her recently deceased grandfathers attic for things to keep/auction off and so forth. The player would then have to inspect things and figure out why some of the stuff in there has strange markings and mysterious connections.
I intend to focus on things to be added now and will sit down to start on a 3d Cello tonight.
