<p class=MsoNormal>Hello,<br>
<br>
I am trying to create an add-on for real-time distributed modeling. At this
time it looks like I need to keep the various instances of GME working on a
consistent model, meaning, if someone creates an object, it should show up
exactly as created on the other side. I am having trouble finding ways to
create objects with a specific ID.<br>
<br>
Can someone help me here?<br>
<br>
