That surprises me. tilemaker produces vector tiles compliant with the Mapbox Vector Tiles spec and I thought that's what OpenMapTiles understood. I think this will require input from someone who...

@dmrotar This is great - really good to hear your experience and that it worked for you. A couple of thoughts: > modified to compile with LuaJIT (which I think...

@kleunen I've not used tile-join but I'd guess that the .mbtiles it's creating don't contain the [additional metadata](https://github.com/systemed/tilemaker/blob/master/CONFIGURATION.md#additional-metadata) that some clients need - either that, or it's malformed in some...

Hm. That might be a result of the filtering by area that we do in the Lua profile - any small areas won't be written at lower zooms, so if...

Another good reason to create some landcover polygons for low zoom levels :)

Ugh, that's insanely complex. Unfortunately something that big is going to be near-impossible to reduce to a testcase. One possible reason is that Tilemaker can't cope with non-closed inners, and...

Yes, that does look like an issue with non-closed inners (the break at the top island is exactly where that would happen).

I've just pushed https://github.com/systemed/tilemaker/commit/12cb7422fa5431fbf52967daffcabf7c76d1fa21 which will piece together multiple ways to form an inner. It seems to fix both of the above examples on a quick test, though I've not...

Can you tell me where those are? And what zoom levels?

I don't see any issues at z10, but at z9 various islands start getting dropped. I certainly don't see any renderings like the above, but different clients may of course...
