3DS Max - Cap hole with polys intact

BraXzy · Feb 2014

I've been looking for how to do this for awhile and never found out so have done this manually but I am hoping there is a way. When capping a hole, in the back of an object for example.. is there a set way to make all of the loops connect? So rather than having a huge N-Gon you instead have a bunch of polys connected to the stuff round the side.

Here's a script I wrote that'll do what you're asking. It only works in Editable poly mode (never got around to adding Edit_Poly modifier support), but maybe it'll work for you're purposes:

--ASSUMED: in editable poly mode, with one or more borders selected. Edit_Poly modifiers not supported.

allEdjs = polyop.getEdgeSelection $ as array
curSubOBJlvl = subobjectLevel
subobjectLevel = 2

--Find out how many borders their are among the edge selection, and store them each separately.
allBorders = #()
allBordersFlat = #()
curLoop = 1
for i in allEdjs do
    (
    if ((finditem allBordersFlat i) == 0) do
        (
        $.EditablePoly.SetSelection #Edge ((polyop.getBorderFromEdge $ i) as bitArray)
        allBorders[curLoop] = $.EditablePoly.GetSelection #Edge as array
        join allBordersFlat allBorders[curLoop]
        curLoop += 1
        )
    )


curLoop = 1
while (allBorders.count >= curLoop) do
    (
    --Crawl from the first edge to two adjacent ones, then afterwords do the rest in a loop.
    curVrts = polyop.getVertsUsingEdge $ allBorders[curLoop][1] as array
    curEdjs = polyop.getEdgesUsingVert $ curVrts[1] as array
    buff = polyop.getEdgesUsingVert $ curVrts[2] as array
    join curEdjs buff

    keptEdjs = #()
    for i in curEdjs do (if ((finditem allBorders[curLoop] i) != 0 and allBorders[curLoop][1] != i) do (append keptEdjs i))
    $.EditablePoly.SetSelection #Edge (keptEdjs as bitArray) --quick and dirty way to remove duplicates
    keptEdjs = $.EditablePoly.GetSelection #Edge as array


    --Start loops--
    finalEdjs = #(keptEdjs[1], keptEdjs[2])
    latestEdjs = #(keptEdjs[1], keptEdjs[2])
    loopKill = 0
    for i in allBorders[curLoop] do
        (
        temp = #()
        for k in latestEdjs do
            (
            curVrts = polyop.getVertsUsingEdge $ k as array
            curEdjs = polyop.getEdgesUsingVert $ curVrts[1] as array
            buff = polyop.getEdgesUsingVert $ curVrts[2] as array
            join curEdjs buff

            buff = #()
            for i in curEdjs do (if ((finditem allBorders[curLoop] i) != 0 and (finditem latestEdjs i) == 0 and allBorders[curLoop][1] != i) do (append buff i))
            buff = join buff finalEdjs
            $.EditablePoly.SetSelection #Edge (buff as bitArray) --quick and dirty way to remove duplicates
            buff = $.EditablePoly.GetSelection #Edge as array
            
            finalEdjs = (buff as bitArray)
            temp = (buff as bitArray)
            
            if ((finalEdjs as array).count == (allBorders[curLoop].count - 2)) do (loopKill = 1 ; exit;)
            )
        latestEdjs = temp
        if loopKill == 1 do (print "killed" ; exit)
        )

    $.EditablePoly.SetSelection #Edge (finalEdjs as bitArray)
    $.EditablePoly.Bridge ()
    curLoop += 1
    )
    
subobjectLevel = curSubOBJlvl

Ah yes, the one I wrote is basically just for mass bridge-capping on lowpoly models, miauus one is more for highpoly and stuff that's not geometry constrained. Both are useful for different purposes.

Holy crap exactly like that. I'm surprised it isn't a standard feature. Thanks to both of you for the help

http://allesimfluss.biz/ also has primarily quad-based hole capping, that allows you to refine interpolation, and surface flow

So no one notices that triangle at the mid/bottom left side?
oppsy was i not supposed to mention it.

its not an even sided hole, obviously there will need to be a triangle somewhere, and if it were even sided, it wouldnt be there.

oppsy, just saying
