I tried a very basic thing- extruding an edge. Here's how I did that:
1 - Created Geometry container, got into that container and deleted teh File Node inside of it.
2. Created a Tube SOP in the Geometry container, changed its type to Polygons and set Rows 4/ Columns 20.
3. Selected an Edge and pressed L in order to select the whole edge.
4. With the edge selected, I pressed TAB whith my mouse over the Viewport and created a PolyExtrude SOP.
5. Now I pulled on the Gnomon in order to extrude the edge in positive Y direction…most parts of the selected edges were following but one part was moving in the completely opposite direction (negative Y).
No matter what I try, this is happening over and over again and I cannot find an explanation…do you?
EDIT:
Ok, polyExtrude works well if I just extrude with the default number of rows, If I put in anything but 10 the extrusion goes nuts. Maybe a bug.
See the image and hopefully this will explain anything.
