BUG Report:
- Create a structure
- In the structure create a new variable as a “attenuation settings”.
- Create a Data Table based on this structure
- Open the datatable (maybe already crash here!)
- Create a datatable entry
Now every time you open this datatable in the DT editor or click on an empty area in the DT editor or simply change the windows-task - UE4 will crash!
With this bug it’s not possible to save attenuation settings with a datatable at the moment.
You can avoid this problem when you create a sound attenuation blueprint and save in the DT structure a variable as “sound attenuation reference” to this blueprint.
Crash-LOG:
Unknown exception - code 00000001 (first/second chance not available)
