I think you're looking in the wrong place for that sort of information.

Hi, vishalkhanna: To achieve the photorealistic appearances you need to take your Sketchup model into a Rendering application, such as Kerkythea, VRay, Shaderlight, but not limited to these. To have a photorealistic animation/video you would assemble sequential views in a video editor.

I'm more interested in your version of Sketchup.
