LEMs can also be made invisible by checking the hidden LEM option in the material editor. LEM materials can be applied to any face in your SkethUp model an used as a visible illumination source (like a lightbulb, neon sign, etc.) Unlike Omni and Spotlights, Podium LEM materials use actual SketchUp geometry to cast illumination into a SketchUp scene. You can see the light group in SketchUp's outliner. The omni light/ point light is a SketchUp group called a light group. To insert an omni light or point light, click on the point light icon in the tool bar and drag an omni light into the model. Omni light or Point light is an artificial light source which emits light uniformly in all directions, similar to a light bulb. When sun light is on, you can use Podium's Physical Sky to create a realistic sky background with atmospheric qualities such as turbidity and realistic tonemapping. The sun's brightness, exposure and shadow direction can easily be controlled by changing SketchUp's time of day and year in the Shadows dialog. Sun Light is a directional light source that uses SketchUp's sky and shadow settings (SketchUp shadows must be turned on).Sky Light is an ambient light source applied evenly to the entire SketchUp background sky.

These are both "exterior" lights but will have a lot of effect on interior renderings if you are using windows and openings to the exterior. SU PodiumĀ has two types of natural lights. as well as the included Podium Browser content.

You can use standard SketchUp materials, or higher resolution textures from a variety of libraries. When rendered these properties bring the model to life by reflecting light and the environment. Reflections, refractions, bump maps and other advanced properties can be applied to a specific SketchUp materials. SU Podium can turn these plain textures into realistic materials, quickly and intuitively via the Podium material user interface. An essential part of creating SketchUp models is applying textures to faces.
