Sad news about holes...
Double-treble-quadruple DRAT!
EA has changed something in the game. Holes in the wall (or any type of frameless or invisible window) are NO LONGER POSSIBLE! I say 'no longer' because I made a very early attempt at these windows (probably back in August) and they worked back then and I nearly used one of them in my spooky Halloween graveyard. But now, they don't. I've made a couple of 'frameless' windows this week (including a totally invisible window to double-check that I wasn't going insane or anything), as well as testing an older window that used to work just fine (pictured left). The result is that the bottom and top strips of walls remain visible...
I'm gutted about this, and I know some of you will be too (this has been my most-requested Sims 3 conversion to date). I will keep one of the windws in my game so I can check whether this is remedied by EA after subsequent patches (I know patches are not favourite topic-of-the-month at the moment. Maybe one day EA will fix it, but right now, one of my favourite window styles is not going to make it into the game.
