Hi LostScout -

Thank you for your report. I was able to reproduce the crash and have entered a report as UE-16897. I will keep you informed as we investigate a solution to this issue. In the meantime, you can use the DBuffer Decals (if they are turned on in the Project Settings > Rendering) and ALT-Drag them without any issues or crashes.

Thank You Again -

Thanks for the help. However even when using DBuffer Decals I still get the crash. It works fine when duplicating the first decal but the second decal is what causes the crash. It works for a bit but the second decal fails soon after.

I’ve updated the bug.

Does this mean the bug is fixed?

No not yet, I added your information about the DBuffer crash as well to the existing report. While I cannot reproduce it, I want the engineers assigned to work on the issue to have all the information.

Sounds good. Thank you. Would you happen to be able to give a rough estimate of time on how long it might take to get this problem resolved?

Any updates on this bug. Have received two hotfixes for unreal since this inc 4.8.3 yesterday and its still broken.

Thanks

Hi paulr70 -

This crash was a result of a memory leak that was fixed for 4.9 and the fix for this issue has been integrated into that version.

Thank You -
