In this tutorial I will guide you through compositing a 3D object, into a real life scene.
Here is the image I will be compositing the object into if you wish to use it:

(You will need to save it as an image file).
Open up Cinema 4D.
First things first, you need to add the image as your background.
Go to File > New Material in your Materials Manager.
Untick Specular, and then select your colour tab.
You need to add a texture. Go to Texture > Load Image, and select your image.

Close the Materials window, and go to Objects > Scene > Background.
You now need to drag your material onto of your Background in your Objects Manager.
You will now have something like this:

Next thing is to sort out the Output of your scene. Go to Render > Render Settings.
Select Output.
Click the arrow at the top, and under Screen, select 1024x768.

Now under Film Aspect, select HDTV 16:9.
You can close your Render Settings for now.
Next up, you need to position your floor guide so that it aligns with the floor of your background like so:

Go to MoGraph > Text Object.
Position your text to wherever you want it to be. (You may want to take advantage of your different view points to position the text).
Once you're happy with the positioning, and you have your text set up, we need to add a Polygon.
Go to Objects > Primitive > Polygon.
Position the polygon so it fills the space below your text like so:

Now this bits important. Here is a video demonstration so you don't make any mistakes.
(Make sure you're holding down CTRL).

Now right click your Polygon, go to Cinema 4D Tags > Compositing.
In your Attributes Manager, under the Tag tab, make sure Compositing Background is checked, and Cast Shadows is unchecked.
![[Image: 5xhx.png]](http://www.host.talkgfx.net/images/5xhx.png)
Go to Objects > Scene > Light.
Make sure your light has Shadow Maps (Soft) enabled. (In the Attributes Manager, under the Shadow tab).
Position your light infront & above your text. (Again you may need to use your other views to get this right).
You'll now have something like this once you have rendered your scene out:

This example doesn't look fantastic, but it's a good method which you can do a lot with.
Once you know these basic steps, you can create your own scene which will be far better.
