Hi @zxc1987,

Thank you for sharing this with the community! I was able to successfully run your sandcastle demo. Can you please share some more information on your intended use case? I am still not quite sure what is broken here.

Hi @zxc1987,

I am not sure if I fully understand the context here. I may have to take some time to get up to speed with how we handle shaders in CesiumJS. In the meantime, if you think this is a bug that needs to be addressed, I recommend opening up an issue on our GitHub page.

Best,
Sam
