Changing any "parameters" results nothing (cine cam)

Development Getting Started & Setup
,

Hi

I set up cine camera then i orient it to my object in 3d scene
Then i try to change depth of field or other values of any parameters and got nothing
By changing values of parameters - anything isn’t changed on the scene
Changing any “parameters” results nothing

Hey @Staglaitor
Would it be possible if you could take a screenshot to show what you were doing? I don’t know if I understand

Yes, i’ll try to record video but nonetheless i understand that changing value in input fields is extra sensitive
There is no possibility to adjust value in parameter because the value changeing with extra high velocity - where can i corrrect it?

There are a few things you can try to troubleshoot this issue:

  1. Make sure that the Cine Camera is selected in the Unreal Engine viewport. If another object is selected, changes to the Cine Camera’s parameters will not be reflected in the scene.
  2. Confirm that the Cine Camera is active in the scene. If the Cine Camera is not active, changes to its parameters will not affect the scene. To activate the Cine Camera, select it in the Unreal Engine viewport and click the “Make Active” button in the Camera Component settings.
  3. Check the Cine Camera’s settings in the Unreal Engine editor. Some parameters may be locked or set to a specific value, preventing you from making changes.
  4. Check the Camera Component settings in the Unreal Engine editor. Some settings may be locked or set to a specific value, preventing you from making changes.
  5. Make sure that the Cine Camera’s focus distance is set correctly. The Cine Camera’s depth of field effect is based on the focus distance, so if it is set incorrectly, the depth of field may not appear as expected.
  6. If none of the above works, try creating a new Cine Camera in the scene and see if the same issue occurs. If the new Cine Camera works as expected, the problem may be with the original Cine Camera.

Thank you for so detailed explanatiion - i have passed inside it completely

Yes - i didi all that you adviced to me but i can’t show you my problem because of ue5-crashing into windows (permanently)- see youtube video

https://youtu.be/FqJlbAc7FaI

Yes i can “blur” all scene but i can’t blur only back and front of it - i need center of the scene unblerred (sharp)

As you can see on the video with crash - i try to blur blue cubes on front and back but grey-colour object should be visually-sharp

Can you record a little video how to do it using default scene

I see that you don’t leave friends in bad and hlep them to the end :)))))

AS i said before number-changing-velocity is extra high and it confuses newbies but the developers don’t see it.

Can you explain me - why changing “max-f-stop” parameter in so extra small value influences to thу situasion for DOF?
I change this parameter just for 0.01 and got result wheraes the value of this parameter can reach millions and millions? Absurd that confuse people

Why alteration of the value of this parameter change result - why?
0.03 - one result and 0.04 other one?

Thanks

Look at video

@Staglaitor
The change definitely depends on a few factors involved, because what you’re changing with f-stop is the amount of light intake to the camera.

Changing this value like that can allow you to blur the background of things while keeping others in focus. It’s directly involved in the calculations of the diaphragm and aperture of the camera - so subtle changes are going to change a lot.

Let me know if you help with anything else!

When just one swipe of the mous results in 1 million in number and another mouse swipe in inverse direction results (-) millon then with absolute garanee you will miss any chnging in DOF and will make a conclussion that it doesn’t work at all as it was in my case. Definitely it is developer’s fault!

Why 0.01 results in blurring and next value - 0.02 results sharpnesss?

@Staglaitor
My best guess is the relative magnitude of the values you’re inserting - f-stop is a divided value, so any changes like this in the decimal place are going to be multiplying the aperture rather than dividing it. For the reason it changes sharpness - it really depends on the object in view at which distance.

The example f-stop values are from 1.4 - 6.0.

Camera and Cinematics require a lot of mathematics, not only on the side of the computer but the programmer, who needs to frame things that the camera will be able to record.
I hope some of this can help you out,
