Having trouble calling PolyExtrude in an HDK. Nothing happens when I pass it an open curve. If I close the curve, it works. I don't know what I'm missing. Probably related but it also doesn't work if I have a closed curve but then use ConvertLine to get rid of the face.
Here's my code snippet. I have a class derived from SOP_NodeVerb and code is called within cook().
Thanks. I added a parameter drop down so I could switch between creating GA_PrimitiveGroup and GA_EdgeGroup in the code. Yeah, there's probably a way to determine group type based on input but I couldn't see how to do that.
