Hey @watabou, as always thank you for your continued dedication on these great tools. I'm not sure if you caught this yet so I just wanted to make you aware. When a portion of the roof is outside of the actual building polygon, it becomes transparent.
There's several examples in this screenshot: https://imgur.com/a/Cvw6ePx
That's what I meant in the post by "looking like greenhouses" :)
When the Raised checkbox (on the same tab) is checked, the roof details are drawn as if we look at them from a slightly lower position, not exactly top-down. In case of gable roofs, the implementation is flawed: when examined closely, the buildings look like greenhouses. I am not planning to fix it right now, maybe later.
