Hpl Model Editor.. How?

[DnALANGE]

the back i can only see if i turn the whole map...

That is the "problem" everybody has.
There is just NO button to rotate 360 degreas \ 180 degrease..
You just need to ALT-> Middlemouse or ALT-> Rightmouse and move your mouse around..
Like that..
That's how we all do..
Also me, those streets, i jusst move piece by piece..
AND if i need to check something quick, i do it like this ;
ALT+MIDDLEMOUSEBUTTON CLICK IT!
Then move your mouse farward..
Then you can (FLY) around the map.
ALWAYS turn LT ON ( ON -> ON is when you see the LT is IN that little swuary thingy. )
IF you have NOT turned it On, you will go UP \ DOWN.
