At this point, we have levels that we can work with and have play-tested and refined them to the point where we're ready to start polishing them to get ready for release.

Previously, we have been using Prototype to do our indoor level creation. This has been great, but when we want to start building professional-quality levels, we need to start adding more details such as textures to the level.

Different companies and game engines deal with this in different ways. Some will take their prototyped levels and then export them to a file to bring them into a 3D modeling tool, such as 3dsMax or Maya, to create their environment, often converting the original brushes into colliders. Other companies will instead refine their prototypes, add in more details, and then add materials to the brushes that were created; this is the approach that we are going to use.

Now, Prototype doesn't come with this feature, but its ProBuilder tool does. In this chapter we are...
