Sequencer Camera Cuts overexposed after setting realistic light values

I have followed your tutorial of setting up Realistic lighting. My problem is that now the Camera Cuts in Sequencer are highly overexposed and only a blank white renders. I'm not sure how to go about setting up the Camera cuts so as to show the exact same image as within RealCameraActor.

I also can't see my scene at all when I've stopped piloting the RealCameraActor.

Any help would be appreciated thank you.

Hey, yeah hopefully Epic will fix it soon. 

In the forum thread mentioned above someone said this:

"So installing the MovieRenderQueue plugin fixed the problem and seems to render what is in the viewport, even though the CameraCuts still look overexposed."

Maybe that can help you too. 

You are welcome and have a great weekend as well!

Hello,

I managed to finally update my scene lighting to use physical values, and expanded the default luminance range, using a project setting for exposure bias to 0. I appear to be having the same issue as this post mentions - RealCamera actors work fine when placed in the scene and piloted to test their exposure. However, once added to a Sequencer track, the Camera Cut shows them overexposed, while Default Camera and CineCameraActors do not do this.

Moreover, due to the autoexposure setting on the camera, the RealCamera output keeps trying to update as the sequencer progresses, causing quick non-smooth changes in exposure, and grey flickers from time to time during the shot.

One last thing - the Debug Focus Plane becomes essentially invisible (no colour) once the irradiance values are up around 90000 to 100000 lux.

What is the latest on this issue?

Thanks

Hey, all these problems seem to connect to the same problem. We are still investigating but the following may cause this issue. When adding a Cinematographer camera into a Sequence, the Camera Component automatically adds itself and three variables (Aperture, Focal Length and Manual Focus Distance) to the sequence and thus locks them for input from the Real Camera Actor. We are not 100% sure yet but you could try to delete the Camera Component from the Sequence after adding the Cinematographer camera and check, if that solves the issues. Hope that information helps!

Hello Cinematographer Pro team....Any update on this issue? We are now experiencing the same overexposure issue in 5.2. We have deleted all camera components on all cameras to no avail.  Any suggestions?

The image behind the render preview is how dark we have the settings exaggerated (intentionally)  and the (low quality) preview window is the result we get no matter what we do. We have adjusted exposure per camera, messed with the post process volume and deleted camera components and nothing seems to affect the results. Thank you for your help.

This is our intended result as far as look and exposure. We can get the viewport to produce this look but not on our renders.... We use the RC plugin daily to great success, but this problem just started happening today.

Hey YO LABS,

I’m sorry to see you having the same issue. This seems to be a problem with earlier Unreal 5.x versions, independent of Cinematographer. Can you confirm, that this behavior only occurs with the Cinematographer Cameras or does it happen with an Unreal default camera as well?

And just to be sure, did you delete the Camera Components from the Sequencer? I’m asking because you could maybe also mean you deleted them from the camera, that’s why I’m double checking.

“When you add the RealCamera to the Sequence it automatically adds a CameraComponent to the Sequencer as well. Please delete this CameraComponent [from the Sequence] and only ever use the settings of the RealCameraActor. This should fix your problem. We sadly can’t stop the CameraComponent from being added and it then constantly overwrites some values like Aperture and Focal Length. Sorry for the inconvenience and I hope this solves your issue!” - from another thread

And did you try to install the MovieRenderQueue plugin, as described above? The forum thread said it still looks overexposed but the actual export is exposed correctly.

I hope this information helps!
