I know, I saw there is the same thread as this, but there is no answer. I can't convert polys to SubDivs. I used cleanup, too. Tell me other tools or options that might help me, plz, any help!:headbang:

This is the error from script editor:
Error: polyToSubdiv1 (Poly To Subdiv Node): The conversion to a subdivision surface failed:
// This polygon contains an interior vertex connected by less than 3 edges.
// To fix the problem, either remove the edge with the interior vertex, or subdivide the polygon so that the interior vertex has at least 3 edges.
// The indices of the vertices in question are: 468. //
