[4.8.1] Win8.1 - Building crashes if I use a Tilemap in the scene


as soon as I place a Tilemap in my scene, I can no longer build the project. The editor crashes during the first step (building geometry) before doing the light building.

How I can reproduce the crash:

  • open new project
  • import a sprite/spritesheet and create a tileset
  • build a simple tilemap with the tileset
  • place it into the scene
  • try to build

Crash Report:

Unknown exception - code 00000001 (first/second chance not available)

"Assertion failed: !IsInRenderingThread() [File:D:\BuildFarm\buildmachine_++depot+UE4-Releases+4.8\Engine\Plugins\2D\Paper2D\Source\Paper2D\Private\PaperRenderSceneProxy.cpp] [Line: 82]

Hey Calaelen,

Thank you for taking the time to report the issue. This bug has already been reported and entered into our system, UE-18132. The bug is fairly new so it still needs to be addressed by the developers.

Let me know if you have any other questions or need further help.

Thank you,
