I don't know about Sverchok, but you can't really do anything equivalent in Geometry Nodes. At least not yet, (I really hope it will be possible with the new Curve nodes)
We are trying to make it all in Speed Tree. I actually pretty much hate it. So inconvenient . Vertex normals are never right there. As of Blender I used data transfer modifier. You make a shape approximation of a tree ( I used Zbrush re-mesher ) but my guess it should be possible to do in Blender too. Not sure why…
More time I am spending with Speed Tree , less I like it . There is absolutely nothing that wouldn't be simpler to do in Blender with Sevrchok or just Geometry nodes . But I assume it's a matter of personal taste .
Are you sure? Looks like the parent puffiness is a main thing to make normals radial . It's just at few nodes of library trees it still has random deviations. Even after I specifically set to zero all the red +/- values in every field. Anyway a few deviations may be ok and a main thing is backfaces. Too bad there is…
Ok, maybe something changed in terms of naming or the way the tabs are organized, but it looks pretty similar to what it always was. There aren't that many variables so you really should be able to get a good result. Your normals seem pretty radial, maybe not perfectly radial, but they look ok in my opinion. Maybe you're…
