Hi everyone. This is the first time I have seen this one. First, some system info -

Windows 10 Pro 64-bit

32 GB RAM

Intel Core i7-6700k CPU @ 4 Ghz

Geforce GTX 960, NVIDIA drivers 376.33

And I just switched to 4.14 a couple weeks back.

I have been following the excellent “Shooter Tutorial” series and I’ve reached a point where I wanted to extend and expand on what I had made using those tutorials. So I was working on an outdoor shooting-range style level (I’d been iterating on it since the new year). Yesterday, I noticed that the normals on the barrel of my trenchgun looked reversed. To confirm the issue, I went into Maya, picked a few of the normals, and reversed them, then re-exported the FBX.

Back in UE4, I right-clicked the trenchgun model and selected “Re-import”- the Editor immediately disappeared and gave me the “An Unreal process has crashed” window. I thought “No biggie, I ‘Saved All’ like ten minutes ago.” But when I re-open my levels, they look…broken. All the editor icons are flat, 2d instead of billboard-style. And my models appear mostly invisible. Here’s a few examples - tunnel level:

Tunnel section - Maya model which no longer appears. Note the flattened static light icons:

Here’s my outdoor shooting range area:

And one of the barracks models I added in the background, selected in the World Outliner:

Here’s that same model in the model viewer:

And lastly, here’s the shotgun I re-imported. Note the translucency which is not seen when viewing the material in the Material Editor:

Thanks in advance for taking a look at this, and for any ideas you may have. I’m also trying to debug on my end. Happy UE4-ing!
