  1. While not selected or using the Blueprint Editor at Component and after clicked again the “View” button to hide the floor. UE4.5 crash.
  2. Show Grid and Show Flow mush be same high.


I hope you will fix this bug…


Hi ,

Does this occur on a clean project with no additional content?

Yes, its new, i just make Mixamo character and click “View” and a few second not focus or doing or using another application. After clicked again this its cost crashed. And why the “Show Grid” and “Show Floor” not equal or same place? Because can’t check the feet height from floor.

Hi ,

Please create a separate post for the crash so that we can keep track of each of these potential bugs. Thank you.

Hi ,

I was able to reproduce the Show Floor discrepancy with Show Grid and have entered a bug report (UE-4480) to be assessed by our development staff. Thank you!
