While I am unable to make amazing screenshots or anything, I did recieve some pm's about how to get around making a new zone or a continent. I use a fairly simple checklist that can be applied to not only World Designs but also any kind of work you're doing in the modding universe.
Level Design Checklist:
1 -[ ]- Draw a sketchmap.
2 -[ ]- Define Scale.
3 -[ ]- Define Colourpallet.
4 -[ ]- Define Theme.
5 -[ ]- List Objects/textures you want to use for the zone(s). Remember if you are creating multiple zones, you may need t open up a spreadsheet and categorize it.
6 -[ ]- Build terrain FIRST (and texture it)
7 -[ ]- Place doodads
8 -[ ]- Texture around doodads, and add details to finish the zone.
That's pretty much the tasks I go through when building something from the scratch. When it comes to creating the files, I usually do it in this order: create WDT+ADT>level design>dbc editing.
I know that this post isnt useful for experienced users, but it may actually help newcomers who just want to build awesome content. I often see content (and in the past I did it myself) that has no structure, basically just built out of the minds of the editor, this may be fun, but in the end of the day it won't look professional, nor will you learn anything from it (apart from how to use NoggIt).
So basically the list is made to help people who has a dream to do more than just WoW modding. As it can be applied to any kind of level design.
