very good nika , I like the simple separated approach to passing the data between weightmap and new topo. Normally I would try to do this in one stage and would encounter context mismatch between per point > per object. Also the topo problem (in general) of it all getting too complicated has gone away by keeping it like this. Im following your vid but did it with get>polygon mesh > empty and using closest point rather than raycast so I can paint on dinosaur. deleting holes next :-bd

yeah the get closest location node was asking to place him there )))

btw does anyone see any practical usage of it? )))

and i don`t understand whats going on at first branch Get Trex.Trex -> Get ..Topology-> Set Topology
this is because of creation an empty point cloud ? it needs some topology? explain please

yeah sorry its get>primitive>polygon mesh>empty

and is just like empty pointcloud but is a polymesh. needs some ICE topo in this case get from trex

I like technique for getting weightmap context to topo but is really slow when trex is higher geometry count which you need to paint a higher detail weightmap so not so practical for 'live painting' but great for converting from weightmaps afterwards.

also I took out the repeat loop on delete holes because some people don't like that node on this forum ;) but it was not this which is slow - its the closest lookup / raycast to weightmap per point is really slow on delete vertex node for some reason.
