One of my go-too tricks is not working. I’ve previously been able to creating a convincing shower niche by changing the depth attribute of a rectangular wall pass-through to less than the wall thickness. Now, the pass through goes all the way through the wall, regardless of attribute settings.
For this project, I was able to place a surface inside the niche to serve as the inside back, and another on the back of the wall itself to serve as a “patch”. Works for now, but it took more time than it used to. 🙁
