in this example each building have metadata like BIN,but how i can get it in shader

              vertexShaderText: `
        void vertexMain(VertexInput vsInput, inout czm_modelVertexOutput vsOutput)
        {
        int featureId = vsInput.featureIds.featureId_0;
        vsInput.metadata.BIN;
        }
        `

when i add vsInput.metadata.BIN in shader,it fail to compile

@lilleyse @ptrgags can you give me some advice

@chen21439 Property tables aren't supported in custom shaders yet. See #10480 and #9572 for more details.

For now you'll need to do this with a Cesium3DTileStyle.

I'll close this issue for now and leave a comment in #9572
