Hi
For the problem of size maps UVW is when exporting UVW of the TDC in the conning tower, after having double clicked on the window bottom right, for the real size, save in various formats including JPEG, dds, png ...
But still the saved maps in 1024*1002 or 1024 *1006
It's not too bad (just resize the maps), but he must know, for not having error calibrations of textures
Edit : with the test version 1.1.87.0 the UVW maps are good
and with the faces selection is easy to find the good locations
