Thanks Constantine for the topo pack.

Maybe a dumb question , but what is the true node there, i don't remind it.

It's just a limitation of old version, I fixed that already. If you left Clamp parameters at False value all the polygons would scaled and transform. Bu they're not now.

Also Extrude Islands returns proper Top and Side clusters now, please redownload the topo pack and test it if you have a chance

I think i am too green in ICE for this, i thought node "to per point" was to change for example context from polygons to per point but i was unable to do it.

To change context from polygons to vertices you have to build array from set of PolygonToVertices attribute and use "Array to Vertex Set" compound

Thanks. I'll go now studying how changing context works.

Greeble. Well, sort of, some of the features are missing (instancing on top of extruded polygons), they were cut for performance reasons, but still.

Sometimes you should feed a constant set of polygons to make Extrude Islands work. It can be done by building array from polygons you want to extrude and converting the resulting array to set via Array to Polygon Set compound, like so:

This looks very nice, could you do it just partially?

:D haha! curious about the bunny inside the bunny did you made it on propose? Did you extruded polygon islands?

Does it needs Momentum?

No, you should remember that is not a boolean operation, the inner bunny generated automatically by the inverse extrusion, you can check how it works in a compound

Of course not, you can use it for other types of effects, if you find any :D It's so useless, I'm currently trying to figure out why did I spend so much time on this. Anyone tried Grasshopper?
