[Closed] Getting uv shells/elements without UVW_unwrap Mod

ok, just does to me, seems as if there should be a better solution but if not…

Halfway through writing it now anyway

Cheers

for editable poly it will be a little harder. polyop doesn’t have mapfaces < – > mapverts methods

try this one

fn getUnwrapElements myMod =
(
if classof myMod == Unwrap_UVW then
(
modPanel.setCurrentObject myMod
subobjectLevel = 3
facesAr = for f=1 to myMod.numberPolygons() collect f
myElements = #()
 
while facesAr.count > 0 do
(
myMod.selectFaces #{facesAr[1]}
myMod.selectElement()
myElement = (myMod.getSelectedFaces()) as array
append myElements myElement
for faceId in myElement do deleteItem facesAr (findItem facesAr faceId)
)
myElements
)
)
getUnwrapElements $Teapot001.modifiers[1]
 

and btw… there is always and this one

yeah im doing it in mesh

as for the unwrap its a quite well documented issue, a quick google came up with quite a few post about it,

A test i just did

reset max
make tPot
add unwrap – not too bad but still about a second
convert to edit poly – about 5 seconds!

waaaay too slow

just tried it in max 2010, and the convert was almost instant

thanks sinokgr but im trying to get them WITHOUT an unwrap mod

I have already written a script to get me the shells with one

Max 2013 UVW Modifier was broken at first. They had to patch it to fix it. It was basically unusable. FPS equivalent while unwrapping a box was like 2. Now it’s a bit better.

I still wish they would just made the UV part of the SO level or something. I do like how Maya handles that part. But that’s one of the only things about Maya I like…

i have product update 6 installed, its still slow for me

x86 unfortunately but i dont think that would be it, and Nitrus is turned off, regular dx

yeah i have tried turning off all the redraws, it didnt make any difference for me because im doing stack modifications which seem to be the slow bit

Most of my script runs modifications with the create panel active (or anything but modify) and its runs fast, but there are a couple of commands that must be in modify, and that kills it

I was posting about this in another thread, but I got something similar working yesterday to this, I think.

I am using the 2 methods you mentioned to get shell borders, then select those open edges in an EditablePoly Mesh, to show seams without a UVW Modifier. It’s not working 100% though, and the big issue is speed.

Dennis said those 2 methods are slow. It looks like they operate at about 0.1 seconds on an EditableMesh, going through all faces, but 4-5x longer on an EditablePoly, which is not acceptable to me. It causes 0.5-1 second of lag to the user, which will not work.

So he said to look into mapfaces, but now I need to figure that out. I would like to ideally operate on the Mesh, but select edges in both EMesh or EPoly. Since you could have an EPoly, but apply a turboSmooth modifier, and now it’s considered a mesh. But I’d still want to select/show the edges.
