Description

There are a bunch of weird sharp-shaded edges scattered all over the model of the Mk1 Inline cockpit as of KSP 1.2.1. I'm attaching screenshots of the model in both 1.2.0 and 1.2.1; see if you can spot the difference. I expect this happened while the ladder was being fixed.

Thing is, I actually know exactly what went wrong here, because I've seen that specific pattern of messed-up edge normals before. Taniwha's Blender .mu import/export plugin (http://forum.kerbalspaceprogram.com/index.php?/topic/40056-11x-blender-mu-importexport-addon-v100/) is a very handy tool for modders, but it does have its shortcomings, chief among which is an inability to get edge normals QUITE right on import. Take a look at the third image here; that's what the the 1.2.0 version of the model looks like when you import it into Blender with Taniwha's tool, clearly displaying the exact same pattern of erroneously split edges we're seeing in 1.2.1 screenshot.

So yeah, you need to clean up and redo all your sharp edges manually after you import a model from a .mu file into Blender. It's a little inconvenient, but not hugely so. Select the whole model, CTRL+V for Vertices, "Remove Doubles", ALT+click your edge loops and mark em sharp, edge split modifier marked edges only and you're done. Five minutes tops.
