Joining of imported 3D tiles

[pveierland]

Hi,

When importing Google 3D tiles, the tiles do not always correctly align. See example below:

Discontinuity between tiles causes issues when e.g. placing things on top of the mesh surface.

Is this a pure data issue - and if so - would it be possible to create a feature to allow automatic smoothing of tile connection points?

Can you propose a method how to treat the discontinuities between the tiles?

I haven't tried it out, but the naive approach I'd try could be:

• For lines between neighbor tiles, ensure that all vertices along each tile line is present in both tile meshes, then for each vertex in each tile along the line, adjust the vertex z position to the average of the line vertex pair. This should make lines between tiles correspond.
• For corners between tiles, follow the same approach of adjusting the z position of the vertex to the average of the tile corner vertexes.

The old Google Earth Decoder, that is no longer available on Github, was able to pull tiles that were aligned properly, but didn't officially use Google's API to do so; it downloaded the raw glb/jpegs. I would really love if there was a fix for the misaligned tiles, since I would prefer to use a more legit solution to download google's meshes.

Boy was I happy to find this thread and boy am I disappointed to see that there are no possible solutions being proposed. I hope someone comes up with something and if anybody does please let me know

you can try to bridge walls of each tile with walls of neighbouring tiles, but it is very tedious. Or you can try to remesh the terrain in the Sculpt mode and reproject texture and details on it. At least it is what I'm trying to do, it is much better that manually joining the vertices
