Complex buildings or a group of buildings in sloped terrain may collide and result in a building inside building visually in OSM2World, also would give a warning in JOSM but in JOSM that would be subject to "ignore the warning" or set the layers properly -

A few information on the wiki: https://wiki.openstreetmap.org/wiki/Simple_Indoor_Tagging especially notice the image there "Sketch for a slightly more complicated example using building:parts"

and of course this one: https://wiki.openstreetmap.org/wiki/Key:level

I'm sure Tordanik knows about these, given the fact he's one of the contributors/maintainers of these OSM wiki pages LOL

in JOSM I'd get rid of the warnings using the layer=1,2,3, etc..

however to visualize that I guess is the real deal, as then it assumes for sloped areas also that there's an elevation model available, which in OSM2World right now isn't.

And therefore I'd kindly ask to have this somewhere in the pipeline of development.

screenshot example of what happens right now:

I'm still working on the building(s) on the right side they're rather very complex again.. but either way, the part of the office sticking through the roof, is actually 8m below due to the sloped terrain here in the mountains. So although height, level, min_height, etc are set correctly measured from the pointcloud, and where the slope isn't so steep it doesn't really matter, but where we have steep sloped areas I'm hitting problems because of the flat terrain in OSM2World so that would really be a HUGE improvement if OSM2World would use any of online available sources for sloped terrain.

Maybe additionally to that, allow the user the choice between 1 or 2 free online sources and a local digital elevation model (heavily simplified because there's no need to load my 100+GB detailed DEM files of course.. some stripped down "rough approximation" only 100MB big vectorized file would be sufficient for mapping and visualizing OSM Data
