Now that I have a 3D world I can interact with I need some models, the problem is that my experience in that area is little more than sticking textures to stretched cubes. So I went through an online Blender tutorial, brainstormed the models I need, and set myself a challenge of creating a 3D model every day for a month.
That month is now over, and I'm happy with the results. This was an enjoyable and fulfilling process of taking a lifetime of memories of buildings and re-imagining them into something we can see. I found the best quality models to be the ones I created side, front, and isometric sketches of before opening Blender, and that drawing with the mouse is not working for me. I can't consider this finished as many of these models will require touch-ups and in some cases a complete rework, plus there are more models I would like to create, but now I have enough to get started on the game logic. When I come back to this, I'll do it with a drawing tablet and without the strict requirement to create and texture the entire model in an afternoon.
