Description

There is an issue where Point lights with source length building static lighting in the incorrect direction, the axis in which the light to be built seem to conflict with the preview build. This issue does not occur unless the light is set to static. This issue appears to be a regression.

Versions Tested:
4.18.3 CL - 3832480 - Issue does not occur
4.19.0 CL - 3944462 - Issue occurs
4.20.0 CL - 3952118 - Issue occurs

Steps to Reproduce
  1. Create a new project (no template or starter content needed)
  2. Add a point light to the level and set it to be a static light
  3. In the details panel for the point light set the source radius to 1.258
  4. Set the Source Length to 250
  5. Set the Point light so that it is horizontal
  6. Build the Lighting
    Result: The built lighting is not facing the same direction as the preview Lighting
    Expected Result: The built lighting matches the direction of the preview lighting
