[MaxScript] Transfer stack selection to Unrawp UVW
I think its not fair that you should pay something for stuff that should be there by default.
Which is why I decided to make a free script...
And I actually made one. But of cource its very slow and doesn't work for editable mesh and modifiers like edit_poly yet and so on
Here it is:
fn BuildUVEdgeAccordance obj UMod =
(
local EdgesCount = polyOp.getNumEdges obj
local EdgesVerts = polyop.getEdgesVerts obj #{1..EdgesCount}
local ReturnArray = #()
for i = 1 to EdgesCount do
(
UMod.setTVSubObjectMode 2
UMod.setSelectedGeomEdgesByNode #{i} obj
UMod.edgeToVertSelect()
UMod.setTVSubObjectMode 1
local UVEdgeVerts = umod.getSelectedGeomVertsByNode obj
local s = timeStamp()
local j = 1
while ((UVEdgeVerts - (EdgesVerts[j] as BitArray)).numberset != 0) and (j < EdgesCount) do
(
j += 1
if ((timestamp()) - s) / 1000 > 5 then (print "Error in while loop in BuildUVEdgeAccordance" return undefined)
)
ReturnArray[j] = i
)
ReturnArray
)
fn ConvertGeomToUV GeomArray UVArray =
(
(for a in GeomArray collect UVArray[a]) as bitarray
)
fn GetIntSelectionLevel obj =
(
case getSelectionLevel obj of
(
#object: 0
#vertex: 1
#edge: 2
#face: 3
)
)
fn UVWSetSelection UMod obj VertSel EdgeSel FaceSel =
(
UMod.setTVSubObjectMode 1
UMod.setSelectedGeomVertsByNode VertSel obj
/*UMod.setTVSubObjectMode 3
UMod.selectFacesByNode FaceSel obj*/
UMod.setTVSubObjectMode 2
UMod.setSelectedGeomEdgesByNode EdgeSel obj
UMod.setTVSubObjectMode (GetIntSelectionLevel obj)
)
fn MainFunc =
(
local NotificationArr = callbacks.notificationParam()
local obj = NotificationArr[1]
local UMod = NotificationArr[2]
if (selection.count != 1) or (classof UMod != unwrap_uvw) then return 0
modPanel.setCurrentObject UMod
local UVArray = BuildUVEdgeAccordance $ $.modifiers[1]
local VertSel = #{}
local EdgeSel = #{}
local FaceSel = #{}
case (classof obj.baseobject) of
(
Editable_Poly:
(
VertSel = polyop.getVertSelection obj.baseobject
EdgeSel = polyop.getEdgeSelection obj.baseobject
FaceSel = polyop.getFaceSelection obj.baseobject
)
Editable_Mesh:
(
VertSel = getVertSelection obj.mesh
EdgeSel = getEdgeSelection obj.mesh
FaceSel = getFaceSelection obj.mesh
)
)
local ConvertedEdgeSel = ConvertGeomToUV EdgeSel UVArray
UVWSetSelection UMod obj VertSel ConvertedEdgeSel FaceSel
)
TransferUnwrapSelection = MainFunc
callbacks.removeScripts id:#TransferUnwrapSelection
callbacks.addScript #postModifierAdded TransferUnwrapSelection id:#TransferUnwrapSelection
So the question here does anyone know is there any correlation between geomedges indexation in Unwrap UVW and lets say Editable_Poly edges indexation? Or may be vertexes or faces can be used somehow to figure out the geom edge index in Unwrap?
I mean Unwrap modifer is one of the most stupid and poorly designed modifier in max. Just because you don't have a direct access to vertexes edges or faces - you have to physically select them like if you pressing some buttons in modifier interface which so extremely stupid and slow. I mean even simple mesh may freeze your max forever because of this.
So may be there's another way? Like calculating this indexes from lets say vertexes or faces?
Transferring vertexes and faces is simple though because they have the same indexes.
So if someone have any ideas how you can transfer edges - please share this important information
Yeah and I wonder why the hell on earth autodesk decided that making a separate indexation algorithm for geom indexes in unwrap modifier is a great idea... but this is a rhetorical question)))

though it ain't pretty :?
Last time I saw a C++ sintaxis - was in university more than 10 years ago
But thanks anyway I will look at it and hopefully will be able to undersand something.
