Re: How to disabled Pprimitive Object Shadow?

[Sean Lilley]

You can try setting the lighting to flat:

new Cesium.EllipsoidSurfaceAppearance({
    material : billboardviewer,
    flat : true
})

You don't need to set 'castShadows' (which is now just called 'shadows') because by default primitive shadows are disabled.

sample image 

two area color is different 

it's because of lighting
