I ran into another obstacle. In the hierarchy, I have a Cloner and Optimize and Thicken modifiers. The Optimize modifier does not merge vertices.

Sorry, I found it. It is "Optimize"

Hi to all,

just start to use Geo Modifier and I like it. It gives some 3dsmax/Blender modifiers logic. But I can't Weld modifier to weld vertices. Is there some other procedure or there is not such feature yet? It would be nice to have it.
