Firstly, I thought this was the best place to post my question, since there isn't a Maya section or a generic 3-D modeling section, as far as I saw.
I am following a tutorial which can be found here https://www.youtube.com/watch?v=fhPWIDX5iQ0
Currently, I am struggling to figure out what setting I messed with to create such weird effects when I am trying to extrude. Apparently it is dividing every edge connected to the four vertices I am trying to extrude in half, then connecting the new vertices together. You can see the vertices I am extruding in yellow.
Any suggestions on what I may have messed up? I am clueless, and probably don't even know what to search for other than "Strange Maya Extrusion" and "Maya Extrusion Dividing Edges", without any luck. So, anyone know why this is happening or how to fix it?
