Realistic Renders in Blender: Adding 3D Models to Images

Learn to add a 3D model to an image! The first step is to get the perspective of the camera in Blender to match the perspective of the actual camera on which the photo was taken. After that, the 3D model and a plane object will be added to the 3D space. The next step is to make the 3D model form a shadow and, if necessary, a reflection on the surface of the plane object so that they appear to be on top of a surface that is in the image. This makes the end result as realistic as possible. Lastly, an image of the view is rendered.

Skills you will learn:

• using fSpy to define the right perspective for the camera

• forming a shadow on a surface in an image

• forming a reflection on a surface in an image

• using the node editor in the Compositor window

• using rendering layers and collections

• rendering the view into an image

This course is meant for 3D artists who already have some experience with Blender, but if you are a motivated beginner, this course is great for you as well. The programs used in the course, ie Blender and fSpy, are free.

The course includes two exercises that will get you familiar with the process. In the first exercise, a 3D model of a clock will be added to a wall in an image so that the clock forms a shadow on its surface. In the second exercise, 3D models of three coffee mugs will be added on top of a glass table in an image so that they will form both a shadow and a reflection on it. To do this they must be rendered in separate rendering layers and after that those layers will be added on top of each other using the node editor in the Compositor window.

After the course, you can use the skill you have learned to add any 3D models on the surfaces of different kinds of images. This skill is often used, for example, when you want to fill an image of an empty apartment with realistic 3D models of furniture.

Frequently Asked Questions

How long do I have access to the course materials?

You can view and review the lecture materials indefinitely, like an on-demand channel.

Can I take my courses with me wherever I go?

Definitely! If you have an internet connection, courses on Udemy are available on any device at any time. If you don’t have an internet connection, some instructors also let their students download course lectures. That’s up to the instructor though, so make sure you get on their good side!
