CG Spectrum

These include: Bump mapping Bump mapping is a texture mapping technique that simulates small-scale bumps, wrinkles, ridges, and other surface irregularities by altering the surface normals of a mesh but without actually changing the geometry.

However, using a configurator in a built environment presents multiple challenges including 3D meshes changing shape, shadows not lining up, and materials reflecting different lighting and colors. Because the lighting is baked in, it’s difficult to test out multiple lighting scenarios. Photo courtesy of Theia Interactive.

The solution to these problems is to add support for a more traditional lightmapper (pre-baked light texture). Lightmapper looks pretty nice: Of course, GIProbe still has the advantages of being real-time, easier to set up (no unwrap or bake), supports rough refletions (which look great), and light affects dynamic objects more accurately.
