how to edit bgltf file

Hi

I used sketchup to make my model. But they become transparent when loaded into Cesium.

Then I find the solution. That is removing 3042 from the states array in technique0 and technique1 in In the glTF file.

However, the new bgltf is uneditable in common edit tool.

how can I edit bgltf file to solve the model transparent problem?

thank you

Chris

I would recommend you instead change the file in sketchup and then reconvert. gltf/bgltf files are meant to be the end stage of the pipeline and not really meant for editing. It’s technically possible, but there aren’t really any tools around for doing it (though there might eventually be). I think you might be running into a known Cesium issue with some models, but I couldn’t find an issue for it.
