Tears in faces

Hi

While editing my level (Shootergame preset) I get tears in the faces of some of my walls and floors. At first I thought it was a lighting issue, but when I play it my character can shoot and fall through the holes made by the tearing.

Anyone know how to fix this?

example:

Hey Zaxaya -

At first glance I am not 100% sure but it looks like you might have one of two problems, a subtractive BSP in the way of your wall, or (and more likely) you have some off triangulation going on which needs to be addressed and is problem causing the rendering errors in the map.

I have marked it on you image here:

Hi Eric

Thank you for your response, I am still fairly new to UE4 and have no idea how to remove the triangulation. Also, making a new BoxBrush and replacing the old one with the new one creates a new set of these holes.

I hope to hear from you soon

Hey -

Do you have any subtractive brushes that might be intersecting with your walls?

Thank You

Hi

I’ve checked and no subtractive brushes are intersecting or even close. If I remake some of the walls and floors which are close and/or adjacent, the pattern of the hole(s) change

Hey Zaxaya -

The walls that are creating these holes are they compound in nature or extruded or are they merely boxes that have been pushed together.

Thank You

Hi

The walls are all box brushes which I’ve transformed by moving vertices and faces.
I’ve asked around and some say this issue is due to the fact that I might have inverted meshes. Any chance if this can be the problem and if so, how can I find these meshes?

Yes this is the odd triangulation that I first mentioned in the above image. If you are using BSP boxes you should never have the diagonal line that I pointed our above. I would go into wireframe mode and select each BSP individually and look for that sort of diagonal cross line and try to see if you can straighten it or replace the box itself.

Thank You
