Using these render ready light fixtures can greatly reduce the time involved in setting up the SketchUp model for interior lighting. Podium Browser provides hundreds of free, render ready light fixtures that have artificial point and spot-lights carefully configured for accuracy, and ready to render. Podium Browser Light Fixtures: SU Podium V2.5 comes with a companion plug-in called the Podium Browser. This is a powerful feature that lets you hide the light source but creates an evenly distributed light, and is extremely useful for creating behind camera “fill lights” to fine tune your lighting. Hidden LEM lights will still cast light into your SketchUp scene, but any surface with a Hidden LEM material applied will be invisible in the rendered image. Hidden LEM: 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.) LEM Lights: 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 & Spot Lights Omni light or Point light is an artificial light source which emits light uniformly in all directions, similar to a light bulb.
An essential part of creating SketchUp models is applying textures to faces.
