I'm curious what issues you're running into @jinpavg
I just started a fresh project with UE 5.5, cloned RNBOMetasound, checked out develop, exported (via rnbo 1.3.3) and built and I'm able to load my node.
This was in windows. BTW, I did have to update visual studio for UE

Hey @x37v , and others --

Indeed, it looks like my issues were on macOS only, and were resolved by updating Xcode and creating a fresh project and a fresh pull of RNBOMetasound -- either main or develop works for me with RNBO 1.3.3.

@CharleyLanusse -- A note that if you are updating your UE project from a previous version of unreal, you'll probably need to clone a fresh version of this RNBOMetasound repo as your plugin. UE seems to have a hard time recompiling the plugin when it has previously been built for another version of UE.

One more note that for some reason, UE crashed the first time I tried to build my 5.5 project with RNBOMetasound included. But when I tried again, it built successfully. The crash seemed to have to do with metadata specifiers for the UE version on macOS, not the RNBOMetasound plugin itself.
