physical_render (1): replace the color key by transparency (e.g.physical_render (2): apply the rendered mask.
#KEYSHOT RENDER NO BACKGROUND HOW TO#
In post-processing, duplicate the realistic layer: Learn alongside Industrial Design Specialist, Brooke Harrington, as she demonstrates how to render still images and animations with transparent backgrounds directly from KeyShot. Set all materials that become transparent to ambient black and all others and the background to ambient white. Then do a mask render by turning off physical rendering (global illumination, shading) and replacing all materials by purely ambient materials without physical properties. First do a physical render of the model by using a material with fully saturated color key and physical properties (glossiness). So the procedure to render would be to do two renders: Most web publishing works better with PNG format. If other regions on the rendered image contain the same color key (number plate, interiors), they need to be masked to preserve their opaqueness. JPEG is the only available option in Keyshot that does not allow transparent background (also called alpha channel), so the transparent background option is next to the format selection. This can be done by rendering a magenta or (lime green) car and then turning all magenta transparent. Camera settings also contribute to the composition: as a rule of thumb, I usually stick between 50mm and 80mm lenses. I believe Renault did post-processing to convert a certain color key to transparency. In Keyshot, the first thing I do is import the data I want to render, and start laying things out to get the composition right. KeyShot allows you to render an image or animation frames with a one-click option to Include Alpha. 
Rendering an image without a background also gives you more flexibility for layouts in Illustrator, Photoshop, or your website. When you project light, you get information about light color (or no light) but no transparency. KeyShot is commonly used to render product shots with transparent background to use across web, print, and video. Renderers typically output something similar to a physical process.
