The environment controls are not great for tiles that are sparse, though, with no objects to zoom in to easily.

Hi @Ylannl! Yes currently the tiles renderer loads all tiles from the root of the tile set down to the target ones. This has become more noticeable specifically as tile...

> Does `Line2` support materials array? Yeah I'm using it my project. You just have to add groups to your geometry in order to use multiple materials: ```js const line...

@Mugen87 > What is actually your use case for using groups with instanced lines? It's what I mentioned in https://github.com/mrdoob/three.js/pull/20861#issuecomment-741263216. I add two groups and materials to the Line2 Geometry...

@Mugen87 I've updated the PR so the material with the largest line width is used for raycasting if there are multiple materials. The code I've presented otherwise runs and works...
