"Preproduction Blueprint" is a complete system for planning your game environments and level designs. This could be for a playable level or a game environment exploration to show off in a portfolio.
Planning process is called pre-production and what you end up with is a "Preproduction Blueprint". It is an essential step to finishing your projects. Unfortunately, planning tends to be a rushed part of the process or completely ignored.
Creating a game environment or a level design is very similar. Once you have an idea you have to go through the steps of:
Rushing into a level design or game environment without planning will most likely result in unfinished project.
All you need is a solid plan of what your environment is going to look and play like prior to creating it.
"Preproduction Blueprint" is the planning system and workbook. These are the same steps I use to design environments and levels. It took me years to figure out and to refine so you don't have to. I laid everything out for you to use in a step-by-step process.
After going through the book, you'll be able to close your eyes and walk through the environment. The level will be finished in your mind. The next step will be to open up a level editor and begin construction.
