Lighting & Lighting Builds

Notes

1. You can also adjust the direction of the light by using the transformation tools.

2. There are two main lights; a spot light and a point light.

3. The third is a; Directional Sky-Light AKA. Sun

   1. Like the other lights, this can be adjusted using the rotation tool. This will change the angle of the sun.

   2. The directional light is also connected to the skysphere that creates the sky. In the world outliner, it is called SkySphereBlueprint.

   3. Every time you move the directional light you need to refresh to sky sphere.

4. You can build the lighting separately by clicking the [dropdown arrow] on the build button and selection [build lighting only].

   1. The medium quality setting should suffice for most uses.

5. You can still work while your lighting is building.
