Problem with the build of Unreal Engine 4.27 with ZED Livelink plugin

Software
1

Dear developers,
I’m trying to add the zed livelink plugin to Unreal Engine 4.27.1.
I followed the instructions shown in this link: GitHub - stereolabs/zed-livelink-plugin: ZED LiveLink Plugin for Unreal
After checking the presence of the ZEDLiveLink in \Engine\Binaries\Win64\ (as shown in point 5 of the Build for Windows → Compile from Source section) I tried to build and run the UE4 project from Visual Studio.
When I build the UE4 project from Visual Studio I get this error:
EXEC : error : Couldn’t find parent type for ‘LiveLinkOrientationsRemapAsset’ named ‘ULiveLinkRemapAsset’ in current module (Package: /Script/ZEDUnrealLiveLink) or any other module parsed so far.

How can I solve this problem?

Thank you in advance for your time.
Best regards.

Hi,

I’m going to test it using 4.27 and see how it goes. I have not this issue with UE 4.26.
Can you confirm that you are using VS2019 to build your project ?

Yes, I am using Microsoft Visual Studio Community 2019

Hi Benjamin,
Do you have any news about my problem?

Hi,

I did not manage to reproduce your issue yet.
I have other compilation errors when I try to build ue4.27.1 that I need to fix first (not related to livelink, but the engine).

If it’s possible, you can use 4.26 to build the livelink plugin as a workaround.

Unfortunately, I cannot use an older version of Unreal Engine. Can you notify me when you have found a way to reproduce my issue?
I have also another question for you: it is possible to develop a plugin for the ZED that doesn’t need the build of Unreal Engine?

Yes, I keep you in touch.

Right now, I am not aware of a solution to generate a program that uses the livelink plugin from UE4 and does not require to build the engine like our current version.
If it’s possible, we would definitely consider the option.

Hi,

I tested with the 4.27.2 release and unfortunately, I was not able to reproduce your issue.

Can you make sure the “Livelink” dependency is added in your .uproject file (see below) ?

uproject

Yes, there are these dependencies in the .uproject file

Did you try to create an empty project (which should compile) and add the LiveLinkOrientationsRemapAsset class after ? You may need to add the Livelink module manually.

Hi @BenjaminV , can you walk me through the work around step by step to make it work with 4.27?
I am going to make a tutorial on youtube so everyone can do it.

Hi,

did you have any issue making it work with UE4.27 ?
Following the Documentation (link : Getting Started with ZED Live Link | Stereolabs) should be enough.

Let me know if you have any issue. I think the best would be to create a new post or directly writing at support@stereolabs.com

Best regards,

Hi,

Can you try to move the UnrealProject out of the Engine folder and try again ?
By “UnrealProject”, I mean the example project available in the livelink sample (this one : zed-livelink-plugin/UnrealProject at main · stereolabs/zed-livelink-plugin · GitHub).

Hi,

I’m sorry but I don’t understand what you mean.
Did you try to remove the UnrealProject from the folder as I mentioned in my last message ?
