Depth of Field in After effects cc 2019 not working with Cinema 4D Renderer option enabled

Unfortunatelly the Cinema 4D Renderes doesn't support Depth of Field or Motion Blur.

The older syster (3D Raytraced Renderer, which is still available on the CC2019 version of After Effects and all prior versions going back to CS6 does, but this is a slower system.)

So here's an alternative:

Create your Extruded 3D shape / text using the Cinema 4D Renderer.

PreComp the Scene.

Now we can make a depth matte to apply depth of field to:

Create a Solid layer, add a Gradient Ramp effect (ie Black to White going Left to Right)

On the PreComp add a 'Camera Lens Blur' and in the Effects Controls, set the Blur Map to the Solid Layer with your ramp on, make sure you select 'Effects & Masks' in the options so the effect looks at the Solid Layer after the Ramp effect has been applies. This will use the ramp as a depth matte creating a very effective depth of field.

You can create a black and white depth matte using any method, not only the ramp, (you can even draw one in photoshop or use a light with a short fall off to create one). The Camera Lens Blur uses this to increase blur values and you can play with the settings and animate the Focal Distance for moving results.

Hope that helps, have fun;)
