That FAQ link is now fixed.<br> <br> I believe that if you use the latest povexport you'll find that the arrow opacity issue has been fixed (thanks to Scott David Daniels).<br> <br> The arrow shaftwidth bug isn't a povexport bug but rather a bug in Visual 5.1, corrected in Visual 5.11. However, if you don't wish to upgrade to 5.11 right away, there's a workaround: In your VPython program, explicitly set headwidth=2*shaftwidth and headlength=3*shaftwidth. You'll find that in your existing program (pre-5.11) if after changing shaftwidth you print headwidth and headlength you see the wrong values, though the correct values are used in the display of the arrow. What Visual 5.11 does is report the values of headwidth and headlength that are actually used in displays.<br> <br> Bruce Sherwood<br> <br> Guy K.
