Hi sstarkov,

This is a big issue that many users are having. It is very important that you follow these steps so that we may get the information we need to figure out this crash. I need you to run the engine with the -d3ddebug command then get the crash to happen. When this happens

To run with the -d3ddebug command:

  • Locate your UE4Editor.exe file. It is probably somewhere like: C:\Program Files\Epic Games\4.14\Engine\Binaries\Win64\UE4Editor.exe (depends on where you installed the Launcher to)
  • Right-click the file > Create Shortcut (a new shortcut icon will be made)

  • Right-click the new shortcut > Properties

  • In the Properties window, in the Target field, after the end quotes, add -d3ddebug (it should look like: …Win64\UE4Editor.exe" -d3ddebug)

  • Click OK. Run the shortcut to launch the Editor with this command.
  • you will know that the command is on by going to your output log and typing “d3dd” in the search bar.

  • Next make the crash happen (make this the first thing you do (it would be best if you did this in a blank project)
  • When the crash happens provide the machine Id (you can post a screenshot of your crash window)
  • Make sure you have log files included (checkbox)
  • Then click the (click here to ciew directory) link, this will take you to the log that will help us a lot with the repro steps please attach that here in a comment.

  • Then click send and close.

Once that is done that should be all the information we need. To summarize we need you to enable d3ddebug command, make engine crash, then submit your machine id/project logs/then submit the crash by clicking the send and close button.

i still have a 100% crash with 4.16.2 when trying to assign weightmaps to my layers:

i usually flood the baselayer then assign a weightmap, then assign another weightmap…so far all good…if i assign the 3rd map i get a unshaded/grey lod0 and if i assign the 4th map i get a 100% crash.

assigning maps at the tiled map import crashes the editor before finishing the operation. thats why i just enable the layers but assign no maps yet with tiled import. but manual map assignement only works for me with a flooded layer plus 2 maped layers…but nothing more

i was using 8x8 1009 maps, on a machine with a k6000 and 64 gig ram
