Attach Visible objects with same material by 300

[n_rangelov]

Hello  i  modified a little bit  the  original script ( Attach by Same Material  )

,so it will attach only the  visible objects in the scene .

I have the following script 

 ---------------------------------------

on attach pressed do

(  

if selection.count == 0 then (messageBox "Nothing selected. To use, select one object and run the script to attach all other objects with the same material.")

else if selection.count == 2 then (messageBox "Multiple objects selected. To use, select one object and run the script to attach all other objects with the same material.")

else if selection.count == 1 then

(

mainobject = $

(

macros.run "Modifier Stack" "Convert_to_Poly"

mat = mainobject.material

for o in objects where not o.isHiddenInVpt do

(

--print o.material

if o.material == mat then 

(

-- print "yes"

mainobject.EditablePoly.attach o mainobject

) ) ) ) )

---------------

But cannot figure it out ,how  to  make the attach to be by 300 objects in one part   - similar to the  "quick attach  ". 

[denisT.MaxDoctor]

fn attachAllToOneByMaterial node:selection[1] =
(
	if iskindof node Editable_Poly do
	(
		for n in geometry where not n.isHiddenInVpt and n != node and n.mat == node.mat do polyop.attach node n 
		node
	)
)

/******* just run with selected target object 

attachAllToOneByMaterial()

*/

We could, of course, add some "foolproof" tests, or use some smarter method for a quick attach, but everything should work as it is.

Hello and thanks for the fast answer.

It's working,  but  how can i make it to go by batches of  300 objects  and then finishing in one.

Thanks again

[denisT.MaxDoctor]

For very large scenes, you need a better attachment algorithm (which exists) and perhaps some user interface for "entertaining" during the process (e.g. add a progress bar).

I did modify it like that 

but now i have an issue when i pick a object without material

all visible objects ( with or without material ) are attached to the first object  .

fn attachAllByCount count:100 mat:m  nodes: =

(

if nodes == unsupplied do nodes = for node in geometry where not node.isHiddenInVpt collect node

if iskindof mat Material do

(

nodes = for node in nodes where node.mat == mat collect node

)

InstanceMgr.MakeObjectsUnique nodes #individual

targets = #()

target = undefined

for k=1 to nodes.count while not keyboard.escPressed do

(

if (mod k count) == 1 then

(

target = nodes[k]

converttopoly target

append targets target

format ">> %\n" (formattedPrint targets.count format:"04d")

)

else

(

polyop.attach target nodes[k] 

)

)

targets 

)

-- You have to specify the target material yourself 

-- >>> For example:

m = $.material 

--  You have to specify number of group to attach, material, and nodes

-- >>> By default all visible nodes that maches a specified material are used 

attachAllByCount count:100 mat:m

you have a different problem... you don't read what I write to you in comments and don't try to understand how the code works.

[n_rangelov]

I read everything  that you wrote twice. To  be honest i did my best to understand the code and i am sorry couldn't .

And before i post it here i was trying to do it by myself  but couldn't  do it.

I already changed  that line from :

m = objects[1].material

to

m = $.material

Comment out this line if you want to treat any mat value, including undefined, as a condition.

[n_rangelov]

Thank you for your help  i got to here.

 For progress bar i have no idea .

[denisT.MaxDoctor]

what is the point of attaching objects by groups of a certain count?

I can understand the idea of collecting by the maximum number of vertices or elements, or by the bounding box, by the world region... but the number of members... why? what for?

use this button

to insert the code

[n_rangelov]

I was told that when attaching a big scene that way is using less memory .

[denisT.MaxDoctor]

Who cares about memory these days?

But if you want to better organize a scene, there are groups, containers, xref scenes.... Attaching is a last resort. Very often it is much easier to assemble something than to disassemble it back.
