![]() The background cloud image is casting a shadow by default, and interfering with the foreground of the scene. Use SketchUp's Make Unique texture if you do not want the material property to be applied globally to the same material name. Note: The material properties are applied globally to the same material name. In this case, you may want to turn off the material property, cast shadows. But this will cause the cloud background image to cast a shadow over much of the scene. At times the cloud background image needs to be scaled up to produce a realistic effect. One example shown below is Podium Browser's background clouds. However, there may be times that you do not want a specific material to cast a shadow. This would be simulate the physical world. The default setting is checked to cast shadows when there is sun light or artificial light. This will reduce the overall render time of the hundreds of leaves but still retain high anti-aliasing for the rest of the model.Ĭast Shadows is an option to have a particular material not to cast a shadow in the rendered image. In that case, you may want to have no or low anti-aliasing applied to the leaf material. The anti-aliasing of the leaves could take minutes or longer. For example, you may have a 3D tree model that has a leaf material applied to hundreds of leaves in the model. However, there are times where you want some materials to have more or less anti-aliasing than what the preset has determined. For example the exterior_high and interior_high presets will apply a greater degree of anti-aliasing than other presets except for the fine_AA presets. The SU Podium presets determine how much resampling or anti-aliasing will occur. It is a global setting that is equally applied through out the image. In SU Podium, it is the last step in creating the photo-realistic image. Resampling is an anti-aliasing image process that is used in SU Podium to subtly smooth the jagged edges of objects in the image. See more about artificial and natural lights in the Lights section of the Help pages. In the best case, the material will render black. Worst case, this combination will crash SU Podium and SketchUp during rendering. Warning: Do not apply any other reflection, refraction, or bump Properties with LEM. The LEM light will be displayed but the SketchUp geometry and material will not be seen in the final image. Hidden LEM is a feature that will hide the material and SketchUp face that the material is on in the rendered image. In most cases, you will not need the High Intensity option. Otherwise the LEM light will be extremely bright. When High Intensity is on, single digit power values should be used. High Intensity check box is applied to the LEM Light. ![]() This will turn that material into an LEM Light. Pick a material and apply the light slider. ![]() LEM lights are easy to create and are quick to render. LEM lights are one type of artificial light source in SU Podium V2.x Plus and will create lights that emit light in one direction away from the face of the texture. The Light slider in the material properties will apply an LEM (Light Emitting Material) to the material you have selected.
