Hi one and all,

I am new to node-red, so sorry if this is a dumb question. (I did search the forum and could not find anything)

My question is does worldmap3d support the extrusion of custom buildings via payload. So for example if I wanted to display the building that’s used in the mapbox demo

> <https://gist.github.com/ryanbaumann/a7d970386ce59d11c16278b90dde094d>

what would the payload command be?

Regards  
Tim

Here you go - Same as for the 2d version.

```auto
