Help with directional light

Hi all…
Why when i sect a direciotnal light there the word “Preview” eveywhere?

Hello Seingried,

The preview is a just a verbal/visual indicator that your light maps have not been build yet. This is the engines best guess at what your shadows will look like. So at the top of your view port where it says build. There is a little arrow that has all the options for a quick build. There is a Build Lighting Only and Lighting Quality. The build will build your lights in your scene and calculate how the light will all of your assets inside of that 3D space. The quality will adjust how accurate the lights will be. The higher the quality the longer the build.

thanks :smiley:
