So there I was, giving WED a chance and trying to make something decent with it. It was going well until I decided to add nice little bevel type things on the ceiling, to make the corners look cooler, and discovered that the slice tool can't cut a cube in half diagonally.
Screw WED. How do you people make your levels? I feel like using a model editor like Blender is messy (especially the texturing) and difficult. Is there a brush/block based alternative to WED, that can be used for games that might be sold?

...Unless there's actually a way to perfectly cut things in WED. Then I'd be happier to use it.
