22 Easy Windows for Faster Facades
A totally non-destructive way to fake windows in architecture, but it's unlike Boolean which can get glitchy and add edges to accommodate the modified geometry.
It's cumbersome but this is a technique that I've enjoyed for making holes for windows and doors on buildings, spaceships, etc. Unlike Boolean for the job, this does not destroy or modify the underlying geometry so mapping is a breeze and the method allows constant changes beneath the holes that are filled with window and door frames.
However! Nothing beats accurately modeling architecture and this is just a joyful inaccurate method giving you the chance to change your mind about the construction geometry immediately and constantly. You can then spend that time instead obsessing over other architectural details.
Because this is a peculiar workflow, you can accidentally learn TONS of other modeling tricks and material node tips in this video which could be valuable even to regular Blender users.
For me, this has been a fun and difficult technique for what I want to create. It's fun enough to share, but difficult enough to warrant such a LOOONG video. I try to cover all the bases in regards to strange things that might go wrong for you.
I won't be offended if you watch at twice speed; you might enjoy it more that way too. The Key to success here is organizing objects with Names and Layers and then carefully Parenting - comment for any reason especially if you have some thoughts about streamlining this method.
