Model Lost Face

I use Cesium JS and convert the model * .shp format to 3Dtiles by FME sofware, but when showing the model in monitor, it loses faces, only the opposite faces are visible. Can anyone help me in this problem? Thank you very much

Hello @vuong2208,

It sounds like FME might be creating tilesets with the incorrect winding order on the faces. Cesium uses back face culling by default to improve performance. I would reach out to FME to see if this is a problem they can fix in their shapefile converter.

In the meantime though, you can disable back face culling on your tileset as a workaround. Cesium3DTileset - Cesium Documentation
Set tileset.backFaceCullling = false and you should see your model correctly.

Best regards,
