Bug clipping non-uniform rotated brushes

Steps to reproduce:

  1. Place a brush (BSP Box / Brush actor) somewhere
  2. Make one side smaller, i.e. change the dimensions to 100,200,300 or resize it accordingly.
  3. Rotate it e.g. 90 degrees
  4. Clip off the bottom part of it.

Here’s an image showing the result of the steps above. These “phantom vertex points” are there if you deselect and reselect the brush too. http://i.imgur.com/YEroGRM.jpg
I’d bet the same bug happens with uniform brushes as well, just that you won’t notice it.

And another example where I tried to cut off the bottom part of some stairs. Can of course work around this by resizing each step manually, but that takes a lot more time.

Hi Dinius,

Unfortunately I have not seen this occur on my end. Do you have any other steps I can take or a video of what you are doing I can follow along with? I’m not seeing any specific errors with clipping.

Sure, here you go: https://www…com/watch?v=whTZqxVnsGU

Hi Dinius,

Thank you for the video, I was able to reproduce this and have entered a bug report, UE-21196, to be assessed by the development staff.
