attempting to upgrade project files to ue5... I get this error when trying to generate a new project.

thanks for any help in advance! -Gennaro

Hi @gschian0 The RealSense Unreal wrapper is designed specifically for UE 4.26 and has references in its code that perform version checks, as shown at the link below.

https://github.com/IntelRealSense/librealsense/commit/20a7930681eed73ddd2475646a29bed0abf02d59#diff-6ef71b6febaaf99bfc1a6e6690679392d8afd0bc8eac13a56283990cb37fd7d0R1

Particularly in the wrapper file RealSenseUE.uproject:

"EngineAssociation": "4.26",

I have same problem on UE 5.3

Hi @DryreL The RealSense UE4 wrapper will not work with UE5. A RealSense user shared a RealSense plugin for UE5 at https://github.com/IntelRealSense/librealsense/issues/12262
