Why Camera Tracking is BROKEN In Unreal Engine
Рет қаралды 10,811
9 ай бұрынIf Vive Trackers have stopped working for you in Unreal Engine 5.3 then try this.
Unreal Engine has changed how it handles tracking data from vive trackers. If you are trying virtual production and camera tracking with vive trackers then this tutorial is essential to getting them working.

Hi Joshua, thanks for the incredible video! I do have one question however. Do you think it would be important to run Room Setup to get this working? I'm trying to run this in a studio setup with 4 Base Stations and no HMD, so I won't be able to do Room Setup. And I don't get the Camera tag in Unreal only the head even after changing the tracker's tag and reopening steamvr and unreal, so I thought maybe that could be a cause as well? Your answer is much appreciated! :)

When it comes to in camera vfx can you make more videos about that? For example how to key and grade the video input (is it best to do it in unreal, or is there a software you can put between the input into your computer of the video and the input from the video in unreal? Which device to use to input the video into ue5? How to do this in the software? How to save what you see as videofile? How to make certain layers (for example that you tell ue5: Yoo this rock in should be in front of the tracked video?

I have a few questions. If i want to make a game with full body tracking. Do i need to set all of the trackers to cameras instead of joints? When testing it, will the unreal Identify them and put some place holders objects on them straight away and place them in the scene when i go into test mode?

It helped me to get the Position and orientation of the Vive Controller or Tracker inside Blueprint. But in Unreal 5.3 I can't figure out what the node I should use instead of "Get Tracked Device Position and Orientation =(

You dont need blueprint. Do what I do in the tutorial and add the livelink component to your camera. Job done.
@themessengerofgood 5 ай бұрын
@@JoshuaMKerr thank you for your response! I've developed an extensive setup within a blueprint, incorporating my custom UI interface, primarily for creating high-quality previsualizations for movies. Within this custom blueprint, I am utilizing 'Get Tracked Device Position and Orientation' to obtain the tracker's transform. Subsequently, I calculate its specific location and orientation as required for my project. Given this context, I am inquiring about the method to accurately acquire the Position and Orientation of the tracker directly within the blueprint."

What happens now is that with this solution, the newly created project can be used, but after a few days, when the project is opened again using this method, the Tracker data disappears. I have been dealing with this problem this week. Today In the end, the solution was to create a new project and then migrate the previous project. I can't understand why EPIC used a good solution in the UE427 era and abandoned the simple and fast solution before a better solution came out.@@JoshuaMKerr
