Crash: BSP stair + no automatic BSP build

Development Platform & Builds
, , ,
1

I have tried unchecking Edit->Editor Preferences->Level Editor(Miscellaneous)->Update BSP Automatically which resulted in getting occasional crashes when working on BSP after multiple level rebuilds. If I enable automatic BSP build again I am not getting any BSP related crashes anymore.

Especially related to stairs since this is where I got all crashes.

This happens in 4.4 (might have happened in earlier version too as I did not test it there).

EDIT:

How to reproduce it:

  • Open new level
  • Uncheck Edit->Editor Preferences->Level Editor(Miscellaneous)->Update BSP Automatically
  • Drag BSP linear stair into level
  • Switch to Geometry Editing (Shift+5)
  • Switch to rotation gizmo (press Space)
  • Rotate stair (for example 90°)
  • Change Num Steps to something like 3 in the Details window
  • Try to switch back to translation gizmo (press Space)
  • Editor crashes upon right-clicking into the viewport and moving mouse a little so that it gets focus so that you can switch gizmo

Hello, stfx.

Can you give me your dxdiag? If you sent in a Crash Report (from the popup that appeared after the crash) with a comment, telling me that comment will help out too.

I played around with it a bit more and was able to reproduce it (see the post at the top). Not sure if this is how it happened for me earlier but it looks like the same crash reason.

Hey stfx,

Good job hunting down those repro steps! I managed to reproduce it here, so I’ll go ahead and report the bug internally.
