I set a customShader for Cesium3DTileset and want to receive the value of prop1.
In Feature, a property named prop1 is set by setProperty.
According to the guide，it seems to get value in the fragmentShader as following:
float propValue = fsInput.attributes.prop1;
But it doesn’t work.
What is the correct approach？
I used the cesium 1.124.0.
Hi @Zhendong_Wang, welcome to the community!
Can you provide a little more information about how this prop1 is generated? A Sandcastle example would be very helpful.
Usually I would expect custom properties to be set as metadata, so they would be accessible from fsInput.metadata.prop1, similar to the Custom Shaders Property Textures Sandcastle. But I don’t know how the data was generated in your case.
