Importing to UE4 without smoothing? I have a model I'd like to export to UE4 but I'm going for a low poly "look" and want to keep the jagged and blocky look it has. Is there a way for me to export it into UE4 without the smoothing effects?
Firstly, follow LuckyCOINNNN's suggestion (although I wouldn't recommend using the split edge modifier, as it will separate all your edge verts), or go to the data tab of the object and enable Auto Smooth with a value of 0 (if you are doing this method you must select all faces and set to shade smooth first), or you can select all faces/verts/edges and set to Shade Flat.

Secondly if you're using FBX to export to UE4, in the Geometry section of the exporter set Smooth to Edge (I think Face also works).
