With a little judgment, you can combine your render with a surprisingly wide variety of backgrounds that swing the mood dramatically while increasing believability. After rendering, combine V-Ray’s transparent rgb output or alpha element in your standalone image editor to composite in different backgrounds. This can be used to great effect in postproduction. 💡 For exterior scenes, the background – the sky – often is prominent. ⚡ Orchestrate the right mood by compositing in a different background.
That way, you can keep all rendering elements in one photoshop-compatible file. 💡 If you are a Photoshop user, install the free Photoshop plugin Exr-io to open V-Ray’s multi-layered exr files. ⚡ For complete control of layer compositing, masking and more, use a standalone image editor like Adobe Photoshop, Affinity Photo, or similar. Set its default level to be so strong as to be unmissable. If you are working late at night, remember to turn off your computer’s automatic night light feature that otherwise ruins colour grading. These include colour temperature, backgrounds and foregrounds, curves for hue, saturation and luminance, lens filters, lookup tables, and similar. 💡 V-Ray ships with basic postproduction tools in its frame buffer. ⚡ Use postproduction to make your render put its best foot forward. Professionals never just publish the raw render. 💡 A common beginner mistake is to be too eager to deliver the result and let the raw render walk out the door on its own.
Postproduction is simply the editing that you do to the raw image after the renderer has finished. Just as Hollywood would never release a film that is not colour-graded, 3d artists should always post-produce their output before publishing. Even though the render has finished, we are not done.
