It should generate the .LSB after shader compilation. (The D:OS 1 editor had a manual shader compile button that you had to click to get the LSB; now it automatically compiles when you save the material). I suppose that since it crashes, it is unable to generate the .LSB.
Gotcha. That's what I figured. What's weird is that the HLSL - DX11 files get generated despite the crash. So you end up with a folder full of all the shader files, but no compiled LSB.
