Hi!

Well, there are a couple of issues with your code. I just read it very
quickly (I don't have a lot of time right now, sorry), but here's what
stood out:

1. You can't do all that work in the connect_accept callback. You need
to use more callbacks, and do the proper step in each. You can create
your nodes in the connect_accept, but you can't create layers until
you know the ID:s of the node you created. You need to do that in the
node_create callback(s).
2. As Amir pointed out, you must create a properly labelled link from
the object node to the geometry node, to define the relationship.
3. It is also recommended, and clearer, to wait for the layer_create
callbacks to use the proper layer ID:s (even though ID:s 0 and 1 are
well-known).

In short, I recommend that you read
<http://projects.blender.org/plugins/scmsvn/viewcvs.php/trunk/verse-tests/geotest.c?revision=2700&root=verse&view=markup>.
It's a bit more than you aim to do, but it should show the "proper"
way to structure a Verse program.

As always, thanks for your interest in Verse.
