@zipit I don't get why you're still not working in Maxon. That seems illogical!
Many thanks for a such detailed answer once again!
The problem is the solution is intended to chew a lot of polys and there may be some "Zbrush"-like model. So as I already understand, I will have to port it to CPP anyway.

@nophoto said in Get all neighboring points (including not connected by edge). Fast.:

I would use a BaseSelect to 'collect' all points

Quite a point! Great suggestion I think, I will try that out

@PluginStudent oh God! You helped me so much!
Many thanks for that. Sincerely, it's not very well explained in docs, really not well (in opposite to Undo system for instance) and getting how exactly should it work is tricky. But your last suggestion surely works, and it raises the number every time hierarchy is changed, so I need only check has it been changed or not and than decide to run the code or not (maybe somebody will stuck in the same position so I hope my plain explanation would be useful)
Thanks!
