Materials

KeyShot offers a big photorealistic material library, and we can select whatever we prefer from the library menu on the left hand side and drag and drop it on the object. We can then customize the material from the project menu under the Material panel.

Rendering the beauty pass

When I'm satisfied with the scene I just need to render out the beauty pass. To do this, just click Render, change your resolution as you want and the Format from JPG to TIFF including the alpha channel. For the quality, I usually use the default setting because it's already fine. Now we're ready to click Render.

Rendering

The render will take just few minutes (of course, this will depends on your computer, but trust me – it's pretty fast). After that I render out an Occlusion pass. We'll need to keep the shadows under the car a bit darker, so to do that we need to select all the objects in our scene and click Link materials. Then select the Edit Material settings, and from Type select Diffuse to get a uniform matte material, and remember to change the color to white/ light grey.

White HDR

We can go now to the Environment panel and under the background section, change it from the backplate image to Color, and from the Environment Library we can drag a total white HDR into the scene. If you have a result pretty similar to the image below it means that it's correct and we can now render out the Occlusion pass as we did previously for the beauty pass.

Compositing

The post-production process is pretty simple. Once all renders are done we merge the backplate, Occlusion and Beauty passes together and play around in Photoshop with levels and curves just to give a bit more contrast and reality to the image. As a final trick I usually copy and merge all the layers, convert the layer on the top in grey scale, and change the blending from Normal to Overlay (changing the Opacity a bit otherwise you risk making it a bit too strong.)
