We made the signals as it is in real life with low polys 3Ds and realistic textures in most cases. The aspects and all the code made according the signaling regulation of OSE using many tricks called in Greek "patenta". We, the Greek route team, we are proud because we thought our signaling is one of the most functioning and reliable signaling system in all the freeware routes.
We also made and use a big part of steady signals like speed limits signs, shunting signs etc. to make your driving easier and without using the F4 screen. With Greek signaling system, F4 screen is useless...!!!!
