This might seem like an old topic by now (had to search through 3 pages), but all the time between the this post and the last, I've been working on a rope bridge.
I had to rebuild the model 3 times, because the scale was wrong.
I used the lwo exporter node to get the shape of the river and the island in 3DsMax so the bridge would really fit the landscape.
But when the last model was finally done, getting it to the same place as in Max was quite a challenge as well.
But I did it, and below are the results.
Now for a cottage on the island... to make it inhabited indeed
