  1. Open 4.18 preview
  2. Place cinematic camera in startup scene (with 2 chairs and table)
  3. Move camera close to object
  4. Set “manual focus distance 4” far from object
  5. Observe object that is close to camera, that is now between the manual focus distance plane and the camera.

What will occur: User will observe that the object between the focal point and the camera is not blurred from the aperture of the camera. Also some artifacts will occur.

Hi 3Detour,

Are all the other camera settings set to default values? If not, can you provide a screen shot of how you have the cinematic camera set up? Also, for the Manual Focus Distance, did you really mean 40 cm? When I set the camera to 4 cm, the camera shows nothing but static.

As seen in “working-blur-4172.png” the manual focus distance is set to 187cm, min and max focal length do not matter. The camera settings that are not default values are modified only to emphasize the BUG, this occurs with any camera with any value. The BUG is expressing the lack of blur between the camera and the point of focus (focal point, as seen in picture “not-working-blur-418-preview.png”).

NOTE: This BUG occurs in 4.18 official release as well!

Hi 3Detour,

I was able to reproduce the bug and I have logged JIRA UE-51863.

Our developers will be investigating the issue further. Please follow that link to monitor the status of the report.
