Hey there @dredgeho! Welcome back to the community! Many of the features of the Water Plugin are incompatible with VR without modification. I would also recommend rolling your own lighter weight water for VR purposes anyway.
It’s not so much an issue to “fix” it’s that it uses mechanics that aren’t compatible with VR. Just using a simpler water setup that doesn’t use rendering tech that is unsupported. It’s not so much a technical hurdle as it is also a performance hurdle when it comes to rendering everything twice in stereo.
