I'm busy teaching myself UDK and as an experiment I've been trying to implement a shader in the UDK material editor that would give the illusion of the game world being curved. I found an example of a cylindrical world shader for Unity and tweaked…

I came up with the node setup shown in the attachment below which seems to roughly emulate the coderesult.vertex.y -= result.vertex.z * result.vertex.z *_Offset; from the Unity shader. Inasmuch as it moves/curves…
