Hi. Please help. How I can clustering some POI that gettings from tile server? I want clustering bloks, gates and liftgates when they too close.

Clustering is only possible in overlays for markers.
(not for map elements being in map tiles or files)

There is a sample in vtm-android-example contributed by users,
but it is more proof of concept, so it is under Experiments.

You can change the priority of how labels and icons (from map tiles / files) are drawn with the render theme "priority" parameter.

See the render theme documentation for more details.

Looking at render theme schema the "priority" is available for "caption" and "text" tags.

yes, but I have only "symbol" tag

<m k="kind">
            <m zoom-min="17">
                <m v="bollard">
                    <symbol src="assets:icons/barrier/gate.svg" />
                </m>
                <m v="block">
                    <symbol src="assets:icons/barrier/gate.svg" />
                </m>
                <m v="gate">
                    <symbol src="assets:icons/barrier/gate.svg" />
                </m>
                <m v="lift_gate">
                    <symbol src="assets:icons/barrier/gate.svg" />
                </m>
            </m>
 </m>

It is a 3D map, priorities are needed in labels, symbols work differently.

Please study the render theme documentation and see the default themes.

Hint: you can use the select="first" parameter in the symbols group.
