Thanks, my code looks like this now: fn appendToParent p children transforms=( for i=1 to children.count do(  children[i].parent=p  in coord…

Sory my bad english again, I just need to thet the child transform relative to parent.

Sory, not really understanding, why inverse? Also this was just a special example, normaly parent transform can be not only identity matrix. Also I no…

Also what about the code, I´ve posted, can it worck?

Klvnk: the 36 is the maximum map verts the box could have assuming none of the map verts are shared ie if you “exploded” the mapping. Yes there is a…

OK; I see, but it looks like the standard box uses just 12 mapVerts. However is there a way to fix such vertex mapVert mismatch?

Shouldn´t it be 24 map verts? At least 8*3=24. Also how can I fix such kase, so the mesh has the same number of vertex and map verts?

Sorry, it was my bad english again, I understand what you explained, but since I have no boxes, spheres and other similar geometries, have only meshes…

So it returns just the mapVert for a single vert and map chanel? But why array? There is always exactly 1 mapVertex coresponding to vertex and map cha…

Thanks, will try it. Just for better Understanding, obj is the mesh, mapCh is the chanel (-2 to max 99), but what´s v? Also verts is a 2 dimensional a…

OK thanks, but what about my problem with makeUniqueArray and my question about polyop?

Yes, I understood that, but it not so much only about 1:1, more important is index matching between vertex and coresponding mapVertex. Also like I sai…

Klvnk: it’s not pretty or particularly fast… fn GeoVertToMapVert obj v mapCh = ( faces = (polyop.getFacesUsingVert obj v) as array …
