Creating a gallery mesh

This section should feel pretty familiar at this point because we’ve taken these steps many times before. We’re going to revisit the idea of using a 2D image as a floor plan and then use ProBuilder to convert that floor plan into a 3D model. After doing that, we will utilize the available materials and assign the materials to our 3D model, and then we can add our lighting system. This is a straightforward implementation, and the approach is easy to follow. Once we have our art gallery 3D model, that’s when the fun begins because we can start creating a system where we can draw in every nook and cranny of it.

To convert our gallery floor plan (Figure 12.1) into a 3D mesh (Figure 12.2) with ProBuilder, follow these steps:

1. Create a new, empty scene and name it ArtGallery.
2. In Hierarchy, create an empty GO and name it ArtGallery.
3. Set the XYZ position to 0,0,0 and the rotation to 0,0,0.
4. Drag our Art Gallery Map floor plan...
