Hi there, Martin Willey from the Catacombs web site mentioned something about this a few months ago and as I explained to him, I’d be more than happy to be able to add my small contribution. My email address is Andrew@Novaclade.com and from there I think the best approach might be to chat via Discord. It’s a particularly good option for me because I can share my computer desktop and show you what I have in terms of CAD files, resources, and my Unity VR project.
Looking forward to hearing from you,
Andrew.
