Creating Photorealistic Renderings and Movies – Scene & Miscellaneous Setup

Before you start, consider what type of rendering you want to achieve – photorealistic, or artistic? There’s no right or wrong way to do a rendering, and it all depends on your intentions and what you want to convey when presenting the rendering of the space to your prospective customer. The answer to this initial question will affect how you should go about renders.

Scene & Miscellaneous Setup

1. Ensure High Quality Models are Used

This is to make sure the models have enough polygons and to avoid jagged edges.



2. Use High Quality Textures and Materials

Ensure that the resolution is high enough, that correct properties are defined (e.g. glass materials should have correct transparency and refraction), and use bump maps if needed (e.g. wood grain materials).



3. Use Photography Composition Techniques to Frame Your Shot

Rendering is just like the art of photography; hence composition of your shots is very important. Use common photography composition techniques, such as rules of third, and consider symmetry, framing, etc.


4. Add Clutter and Imperfection to the Scene

In real life, it is not often that a desk is empty or totally clean; there is probably lots of small objects such as keyboards, mugs, pens and so on. Use accessories in CET Designer (e.g. from the Kitchen Accessories, Office accessories, Plants & Flowers or SketchUp Extensions) to add realism. How often do you come across a meeting room with all the chairs perfectly placed in a 90 degree angle to the table? Probably not very often. They would more likely be slightly turned to the side and not perfectly aligned. These imperfections add to the realism of the rendering.
