I3S IntegratedMesh

[bortomar-intellmaps]

Hi, we have updated to the latest deck.gl v9.0.27 and our I3S IntegrateddMesh (I3SVersion 1.7) is now rendering incorrectly (see first video). It doesn't matter what version of loaders.gl we are using, we tried 3.4.15 and latest 4.2.2, the result is the same. The mesh is extracted with @loaders.gl/tile-conversion slpk-extractor and served by i3s-server.
Is there any configuration option for the I3S IntegratedMesh in the latest deck.gl that we have missed?

If we use deck.gl v8.9.36 the same model is rendered correctly (see second video), no matter the version of loaders.gl.

It is hard to debug from a screenshot. It could be a small issue in the deck.gl code. Have you tested all the examples in loaders.gl? If you can provide a repro, the chances of getting attention improve.

I have the same issue after the deck.gl is upgraded to v9. You can use the following i3s layer for testing. https://tiles.arcgis.com/tiles/6hvouxd2XTE6szh5/arcgis/rest/services/URA_KCAA1_projsite_Jan2024/SceneServer
