Installation guides for UE are confusing

Software Unreal Engine
1

Hi folks!

Seeing that I have so many issues, I wanted to see if I had the last version of everything in order to run ZED uproject in UE5.4. And while trying to uncover that, it became more hazy.

  1. First of all, what is the difference between ZED UE5 and ZED LiveLink and why use one over the other? I don’t believe that is clarified somewhere. I would use ZED LiveLink if it is easier. See point 3.

  2. I remember that when I first installed ZED UE5 via github, it mentioned something about compiling with the help of VSCode. Now there is no mention of that. Did the last version changed the setup process?

  3. I tried installing the new version of ZED UE5, but the tutorial is not very clear eventhough is seems so. I downloaded the repository. I right clicked and selected UE5.4 and automatically a process started. So what happened to pressing Ctrl + F5? And when and how should I press it? Anyway it seems that it installed properly and the project opened in UE. But the UE crashed as soon as I tried starting the L_BodyTrackingMulti or L_BodyTrackingSingle levels. I changed RHI of the project to DirectX 11. It still crashes. So no idea what is going on.

BTW the old project is still working. The one that I compiled. But if I were to do that again on a new pc I would not know how to do it as the tutorial is not there anymore. And I will have to install everything on a new pc asap. LE: I found the tut I used. So it seems you have 2 different tutorials on how you can install Zed on UE. May I ask why that is? And which should I use and why?

  1. How is it with the ZED SDK? I have a Nvidia 4070. Should I use CUDA 12 - TensorRT 10 for both setups that I mentioned?

And this versionis good for both setups, right?

  1. What happens if I don’t make these settings? Because it seems I forgot to do them in the previous setup, and it worked. Or are there new settings related to the new way of setting up the project?

LE: I see now that for the last version of the UE project all these settings mentioned at point 5 are there. So why are they mentioned in the tutorial?

In the end the idea is that the new setup does not work and I am trying to figure out why while understanding how the ZED setup works.

Thank you for clarifying all these points!
