Ok. I have solved the problem of the doors. Another question, if
you go into the cars section of the train folder, exterior,
interior, head, tail, doors, panel, etc. all backgrounds are blue?
What software are the developers using? Like sometimes I want to
edit the trains by myself but I can't find the blue background
colour in Paint? Can you please tell me which software you are
using to develop all these things with a blue background that us
hard to find?
You must have PhotoScape or Photoshop CS5 (better) in order to
edit exterior, interior, head, tail, doors, panel, etc.The blue
colour is to make objects transparent like making the train
doors,windows etc.
