Box Becomes in Some Parts Transparent

Thanks!!!

Hi Jakoozie,

Which version of the editor are you currently using? I was unable to reproduce this on my end. what did your bsp look like before breaking? Was it a simple staircase?

Hi , I’m using the 4.5.1. Yes is a simple staircase I only adjust the vertices in “Geometry Editing” using the Edit Tool.
Thanks!

If you are using the actual stair bsp mesh, I would highly recommend building a staircase with box brushes instead. The stair mesh has several known issues, including the face that moving vertices causes numerous errors with faces. Your best bet at present is to utilize box brushes and create a cohesive staircase that you can manipulate in that way.
