UE4 Crash - Importing Tiled Heightmaps

Am Using 4.10.2,

Have created a bunch of heightmaps; but get a UE4 crash on Import.


Hi ,

  • Does this occur in a clean, blank project with no additional content or is it limited to one project?
  • What steps can I take to reproduce this error on my end?
  • Are the heightmaps .r16 files or are you using a different filetype? What program are you importing the heightmaps from?
  • What specific steps are you taking to import them? Are you using the World Composition Browser?
  • Can you post your crash logs here? They can be found at \Unreal Projects\PROJECTNAME\saved\logs.


Sorry My entire text decided not to paste in because reasons…?

It was in a blank project, with r16 heightmap files. (on a fresh windows install).

I took topographical data, turned it into valid r16 files and just got crashes.

It seems to be resolved by disabling AMDs raptr software (I reinstalled and forgot to disable ze crap :))

Hi ,

I looked into this and it looks like this is something that is very common with raptr software and unfortunately is something we cannot fix on our end, as it is specific to their software. Disabling or removing raptr, as you have said, fixes the error.
