LS3 not appearing but I have Models in Browse tab.

So yeah, I put in the svn for LS3 (Core and Essentials), I get models but not the tab to use it?

Download the Custom Addon Support, or whatever it’s called. You need it to run LS3.

Custom Addon Framework.

They all the LS3 stuff will show up in the CAF tab (it’s in the tool menu. next to Wire)
