I ripped the images from a very old PC RPG, using various modding tools (wich im using to extract sounds, animations too).. then i made a template to paste its parts in it, rezized the images to 65% of its original zize because they can weight up to 30 mbs =S and then very carefully cut its parts and arranged them inside the template, for each piece of map i placed another one to be the second layer..
then i put them in my game, simple draw them and then all the hard work wich is chosing passable tiles, and priorities.
After all that i open the file again in photoshop and cut around every object, arcs, statues in the second layers..
depending on the map zize it takes about 2 to 10 hours to complety finish them and make them playable, but to make them complety bug free takes some more time, and testing whit the character itself
and mm im trying to use "Passabily direccions" as often as i can specially around small objects and such..
i would hate a botchy map too haha so dont worries xD
Will relase a demo soon of the first stage if i can.. once i can solve some ridles whit the Blizz ABS o_o..
It consumes alot of time indeed, but beauty and visual awesomnes has its price xd
