Over the weekend I participated in TOJam 9, my first game Jam

Me and Justin Jacot created See No Evil, A two player split screen puzzle game where one player is blind, but can visualize sound made by the other player, made in Unity & made to look like everything is made of clay.

You can download it and try it out, but it requires game controllers to play.

I programmed it myself, unfortunately a large number of puzzles had to be cut because they weren't working, but the few that made it in successfully demonstrated the concept.

We plan revisiting the project sometime in the future, I would like to finish all the puzzles that we had working and add some polish to it.

I've created an online tool that converts UDK's T3D script into Unreal 4's. Made it to help with the porting of my two buildings "549 King Street" and the CBC building.

Online version v1.0 (only supports static meshes): http://matt3d.webege.com/

v1.0 Currently it only supports static meshes, porting over their location/rotation/scale, any other kind of actor or special properties are ignored. If there is enough interest the tool can be expanded to include other actors like Lights, BSP, etc.

1. You sill need to export all individual meshes & textures from UDK, and import/set them up inside of Unreal 4. 
(with a lot of work, it would be possible to write a tool to convert materials exported as T3D made in UDK, into unreal 4)
2. Once they are in the Content Browser, you can copy the actors inside of UDK, use the tool to convert the output, then paste into Unreal 4.

There is still a lot of manual labor involved while re-importing assets into Unreal 4, but this tool is the first step in reducing the work it takes porting from UDK to UE4
