[Bug] Error: Tile3DLayer: Failed to render layer of type cmpt

[joedjc]

Description

Hi,

I'm trying to load an asset i've uploaded to Cesium ION (a GLB file converted to 3D tiles) in Deck GL (v9).

I'm using the cesium ION loader: CesiumIonLoader

new Tile3DLayer({
id: 'tile-3d-layer',
pointSize: 2,
data: TILESET_URL_2,
loader: CesiumIonLoader,
loadOptions: { 'cesium-ion': {accessToken: ION_TOKEN},
'3d-tiles':{isTileset:true},
isTileset:true,
loadGLTF: true
}
})

Whilst some of the tiles load, I receive errors as some tiles seem to be composite tiles:

I noticed that the loaders gl documentation for the Tiles3DLoader suggests it supports .cmpt file types (https://loaders.gl/docs/modules/3d-tiles/api-reference/tiles-3d-loader).

However, I can't see much other documentation of examples of this - so i'm not 100% sure if it's supported?

Expected Behavior

Cesium IOC cmpt tiles are displayed using Deck GL

Steps to Reproduce

const deckOverlay = new DeckOverlay({
// interleaved: true,
layers: [
new Tile3DLayer({
id: 'tile-3d-layer',
pointSize: 2,
data: TILESET_URL_2,
loader: CesiumIonLoader,
loadOptions: { 'cesium-ion': {accessToken: ION_TOKEN},
'3d-tiles':{isTileset:true},
isTileset:true,
loadGLTF: true
}
})
]})

Environment

• Framework version: v9.0.0-beta-10
• Browser: Chrome Version 122.0.6261.69 (Official Build) (arm64)
• OS: MacOS 14.2.1

In the last 5 years we haven't really seen any use of composite 3D tiles, so we never put any effort into this.

Also the new 3D Tiles standard seems to be moving away from the original set of tile types toward GLBs (glTF) with embedded 3D tiles metadata, so I am a bit surprised to see .CMPT tiles appearing now.

I would say that we'd be willing to accept PRs fixing CMPT, but we are unlikely to prioritize this unless this is becoming a widespread issue (which can e.g. happen when Cesium makes changes to their tiling pipelines).

Thanks @ibgreen - i'm not sure why Cesium ION creates these - we've looked to see if we can avoid them being made but haven't found any. I'll reach out to Cesium to try to understand in what circumstances it uses CMPT.
