Hi there! The rive-unreal-demos are only supported (right now) with the plugin that is included in that repo. Did you get the same problem before replacing the plugin?

I am also running into issues getting the build to work on macOS, but i'm getting a different error.

The newest version of the rive unreal plugin works for me on Windows, but does not build on macOS. Using:

Rive Unreal Plugin 0.3.3a-gh Unreal Engine 5.5.4 macOS Sequoia 15.1 with M1 processor

I’ve tried to make my unreal project a c++ project and build from source as the rive unreal docs suggest. But attempting to build with the rive plugin enabled throws the following error:
