Ah man, I was so close!
I knew collisions were messing it up, only found out how to turn those off yesterday. Also your ordering makes more sense so I've made very similar changes.
All working, hoorah! Thanks for all your help. :)
The picking still confuses me as I feel it's contradictory. But hopefully it'll click into place the more I work with c2.
I would be interested in making this rope bridge object as a plugin for the community, don't suppose you have any tips on where to start? I've seen the SDK area but could use an example "create a simple object" tutorial and can't find one.
