Tolwyn (one of them at least) wants mod authors and talented Wing Commander fans to contribute to an open collection of 3D tools and material available for everyone to use. This is what he had to say.
What is Wing Commander 3D? Wing Commander 3D is a collection pool of mod work. I don't know how willing people are to openly share for the purpose of sharing. I think it's a fairly noble approach, maybe it would go over well. People who made the models for their specific project might have not originally planned on making them available to all. It can be hard to let go of something you worked on, but it's worth a try anyways.
If you've got something you'd like to donate, you can check out more information here. The CIC also has its own limited WC3D section here as well.
