building:part=yes not rendered if only roof is visible

[Nadyita]

Common scenario: I have a building-passage which is covered by a roof only. When I set the following tags:

building:part=yes
building:levels=1
building:min_level=1
roof:levels=1
roof:shape=gabled
roof:orientation=along
roof:height=2.2
height=5

it doesn't get rendered at all. Same when using min_height=2.8. It works when I set building:part=roof instead, but that will give me an "unfilled" roof, not the roof of a house. There are many use-cases when I need something like this, most are building-passages, or just the roof not covering all of the house and the "body" of the house consists of my elements without a roof and then finally the roof is added.

Thanks for reporting this, I believe I've noticed some similar problems and this might help us get to the bottom of it.

However, I have some difficulty reproducing the issue:

The central building part in this example has the tags you provided, and it does get rendered. Can you modify the example file or provide a different one to trigger the error?

Here's an example.zip where it doesn't work. I think I already figured out, how to trigger it.

This node is shared by all 3 building parts. If you remove it from the middle roof, it gets rendered again and all is well.

This is now fixed in 9a94a98. Thank you for the excellent test case! :+1:
