public void setTransparent(boolean transparent) {
        this.transparent = transparent;
    }
Set the transparent value marker.

<p>This value is merely a marker, by itself it does nothing.
Generally model loaders will use this marker to indicate further
up that the material is transparent and therefore any geometries
using it should be put into the {@link Bucket#Transparent transparent
bucket}.

@param transparent the transparent value marker.
