This may also be a good solution. But in this case it can be more difficult to implement and keep it in actual condition. Also it will be difficult to...

Probably it would be possible to show such nodes in menu as inactive. Just example inactivity. 

Another way to solve this is to create scene property for a tree. In this case all viewers of the tree will generate objects according to the property and one...

AN trees have link to a scene by the way. 

This should be super easy to add. Attribute like this `sv_default_color = (1, 1, 1, 1)` should be added to the class: https://github.com/nortikin/sverchok/blob/b96ccce8c2141946612d9cd1624950c4ee7acab6/core/node_group.py#L288

Here is my solution. The idea is to use slice of 3D dimensional Voronoi diagram with Z dimension as weight. [test.zip](https://github.com/nortikin/sverchok/files/8175108/test.zip) 

@portnov Here is the profiling file. Download, unzip and call `pip install snakeviz `, `snakeviz stats` to see where the node spends time except math operations. [stats.zip](https://github.com/nortikin/sverchok/files/8751455/stats.zip) The node spend...

The question is whether it worth to develop those nodes further or to think of some new solution. I'm not sure that with increasing number of such nodes it wont...

My guess is that each node is copying input mesh and modifies only it in GN. They should add feature of mesh inspection for each node via spreadsheets. So it...

I wonder in which collection would we expect to see the object in this case? COL 1 or COL 2 or both?
