Most of what I've managed so far, in experiments, has been accomplished based on the tutorials in that first link and the use of Wilbur (a free app by our very own Waldonrate). To make any of them work, however, you'll need, at a minimum, the TGPGuiLib.dll, along with the SOPack, Firmament and the FEO Plug-ins, most of which should be available through the second link. If/When time permits (still trying to move and have another relative going in for surgery tomorrow), I'll try to post some tips and examples, but it may be a day or two before I can get to that.
