Back-plates are background images that you can choose to make your render look more interesting. You can create your own in Photoshop, or just use a photograph to simulate an outdoor scene. It is so simple to create amazing composting of cars on streets with KeyShot.

Making images better
Here you have a blurred, de-saturated HDR with a light and reflection source. The background is just grey. How can we significantly improve this scene? There is a small trick that I recommend to use, especially to simulate a photo-studio scene.
The process of making your image better
Create a box, or any other shape (the box is the most-used one in these kinds of effects). Place this above the car (or in a position that fits better to your project) and apply a light material. The difference is clearly visible.

Making a curved background
The last tip for this tutorial is to create a curved background, and import it as wall-ground for your project. I suggest making the curvature very soft and big, this will guarantee a very soft gradient in the background of your render.
Why should we import this object? If you go to use a back-plate or color, it will not be reflected on your materials/objects. But as soon as you apply a color to this special object, its color will be reflected on your project.

Different types of backgrounds you could use
The Render settings are quite simple, and they do not really need to be explained. What I recommend is to keep the samples around 16, and the shadow around 6-7 (this is a good project/portfolio quality). Higher numbers will increase the render time a lot. In Passes there is the Clown pass which basically is an Alpha mask, but with different colors for each group – very useful in Photoshop!

I would thank Luxion for making this useful software for designers, and I've included some samples of real-times view renderings here below. I hope you liked this tutorial!
