Allright this time I will try to explain how I did this map in English. First I went to Cinema-Mode of a Map I have played on. I start the Movie and pause it right after. Then I switch to the free camera, which allows me to move around the map free of the character movements. Before I begin to draw, I get a raw overlook of the map. This is nessessary to calculate approximately the space for each map-part on the Paper (since my DIN A3 Papers are somewhat limited 😉 ). After that I divide the paper with a fine line into each half of it. This gives me the approximate center and it is easier to construct four parts than one big part.
The next step I do is to scribble down with a light line the different rooms, buildings. And now the work really starts. I chose a center part, where I beginn to add the details and where I adjust the sizes of the objects. To start with the center is better, than to start with an end, because you can build up the map in circles around that and it makes it easier to get the Ends together in a way they fit. Otherwise you will have problems to construct, especially maps with a lot of ankles like the village, will then lead to bigger corrections. Dont give it up early, for the scribble of the map It usually takes the most of the time (for temple it was about 3.5 hours). After this hard work, the easy Part starts.
You can start with the inking right on your scribble, but to prevent mistakes I usually do a fotocopy.
For the inking I use simple black fineliners, which you can buy everywhere. The challenge is, to have a calm hand and an eye for lines. You can use a rule, but this can lead to even more corrections, which is the reason I do even that only by hand. Make sure you have already thought about how you want to colour the map and if you gonna fill the walls or not and how you gonna show stairs and doorentrys. Because most Maps have more than one layer, think about this while you do the scribble.
The last step is to color the map. I scan the inked version into computer (Yay we can scan A3 at work!) as a tiff or jpg, with 200dpi and usually on a black/white version (to get rid of pencils). You can use Gimp or Photoshop to colour the map. Gimp is freeware and if you think of Photoshop, Elements usually will do it for this. If you have scanned a tiff, you will have to switch to RPG Mode first. Then I duplicate the Layer and make the lower one invisible (this will be my backup if I mess around). I polish the viewable Layer, remove scratches and/or mistakes. After this I change the setting of this layer to muliplicate. The Layers I add after this I add allways below this layer (otherwise you will not see the Lines 😉 ). For each colour I add a new layer. The first layer is the background colour, you can fill it completely with one color. The Layers for the details you will add between the background and the lineart-Layer. With the Selection-tools I chose all the parts which should be in one color and then I fill in the color on a new layer (be sure you are on the right layer, otherwise you will mess up already done work). After the raw colouring I do some finishing work. For example do some gradients or change the colour of the Lineart or simply adding a Title with the Text-Tool.
