LDraw part 118091p looks fine in Part Designer but imports into Studio with extra geo

Eyesight has been made open source (finally) so maybe someone with better coding skill than me can make a standalone.

Ooh, that's good news, I hadn't heard about that! Obviously Blender is open source, and LDraw-to-Blender conversion exists already, but the simplified, standalone UI used by Eyesight is very convenient (if a little lacking in documentation).
