I started off by creating 2 light maps, 1 for the vehicle
and the other for the diorama. I did this in Maya. The process was fairly
straight forward and was very similar to un-wrapping. I simply copied the UV
net across onto a new set and changed the grid size and selected the faces to
be moved in UV space tool. This then spaced out all of my UVs and separated
overlapping UVs so that they were on their own. I then needed to manually move
all of the UVs back into the grid leaving a 2 square gap around all sides and
against other objects.
Once this had been done I then exported the vehicle as an
FBX and did the same process for the diorama UVs.
The next process was for me to import the mesh into UDK and
add my materials into the content browser. I then added several spot lights
into the scene to add lighting. Finally I built my lighting so that when the
scene is played there is light.
