Sketchup rendering item in podium interior12/13/2023 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. 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 Podium 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. For example, recessed ceiling spots are particularly useful.An essential part of creating SketchUp models is applying textures to faces. Instead of stand alone point lights, try to use realistic light fixtures. I would suggest that you use as few point lights as possible because the more you have, the more unrealistic the image will look. Supplementing light fixtures by adding an LEM material behind the camera is also an option but a few point lights in mid-air is often effective in night renders. Use an adequate number of light fixtures in an interior space to provide good lighting. Just as one or two 60 watt fixtures in a room is not enough lighting for a good photo, one or two Podium light fixtures in a interior design is probably not enough for a good rendering. The light fixtures are all calibrated to be realistic. If you are doing a night scene, you can insert the Browser's light fixtures to create most of your lightning. You can turn them "off" by using the dynamic component options. Even if you are rendering a day scene, you probably still want to have light fixtures in your interior design. Rendered with Interior QMC 1.0, size reduced 3 times.įinally, let's not forget about the Podium Browsers' light fixtures. Resulting render with LEMs at the windows and a few light fixtures. This is why it is an excellent way to light up interiors. Podium V2 renders LEM faster than omni's or point lights. Make the LEM material bigger with less power. On the down side, LEMs produce noise when they are too strong so do not use the high intensity option. You can also replace windows with LEM material to give an extra light boost. This is a lot faster to setup, tweak and render then adding multiple point lights. If sunlight alone does not produce adequate lightning, you can use large LEM material behind the SketchUp camera, to give an even light spread. With sunlight, Physical Sky, Sun Intensity/Exposure 30% In many cases sunlight will provide enough interior light, therefore it is recommended to try sunlight first for interior renderings. This techniques is easy and fast to set up and render. Setting the sliders to the max is often a good thing to do when you do not have big openings. (Make sure Physical Sky is on) These sliders still apply to interiors. If you are using sunlight, do not forget to adjust the Sun intensity/Exposure Sliders found in the Environment tab of the Podium option window. For example, remove a wall that is not visible in the scene can get you more sun light. Try to get as many openings to sunlight as you can and orient the sun so that the light enters adequately, if possible. This should be the main way to light up your day time interior scenes. Sunlight produces the most realistic and fastest rendered images. Tip - Lighting up your interior models with SU Podium V2 by Nicolas Harvey, tech support Podium Browser: Light Fixtures, Plants, etc.
