We're still keeping everything fairly high-level and not getting too deeply involved with building the art, however. Proof pieces have almost no mesh detail and usually no textures at all. Instead, we'll be playing with proportions, kit logic, naming conventions, and other basic needs. Because of that, this stage of the process is also relatively quick, often only 1-3 weeks, depending on the scope of the kit, and how many failed iterations of the proof pieces end up being created and disposed of.
Before we can create the first mesh, however, there are several important details you have to know about kit-building.
First, we have to agree upon one of the most important details for any kit - its footprint. The footprint is the foundation of the entire kit. The most common footprints for kits are equilateral, but other proportions can lead to kits with their own distinct feel. These fundamental decisions are very important, as it will influence the visual identity of the final kit. In this image, the green grid represents the footprint of several pieces used to build a simple room from Skyrim's completed cave kit.
It's important to note that although the various sub-kits of one kit do not have to share the same footprint, those footprints should be multiples of each other. Otherwise, even if the kit pieces initially snap together, as a kit loops back around on itself, it will no longer line up. For example, a 512x512x512 room will always tile nicely with a 256x256x256 hallway, but a 384x384x384 room will eventually create gaps and/or overlaps.
