OmniGrid

Omni Grid is a plug-in for SU Podium V2 or for SU Walk that allows you to create a grid of point lights or omni lights above or below a planar surface (SketchUp face).

By creating a grid of omni lights Omni Grid creates a relatively even source of light over a wide space. It is best for interior rendering. An alternative to omni grid is Hidden LEM.
