[Closed] Material add OBJ – custom link checkbox with radiobuttons

What’s the logic behind all that? What IDs and group IDs are?

The “ID” and “ID group” marks are symbolic. I originally thought of segmenting in the form of an ID, but in another part of the code I use something where the ID doesn’t help me.

I would need to link the material list with the object list. If the material is “1”, only the listbox marked “1” will be assigned.

you can store all objects and materials in arrays and simply use selection indexeses of listbox controls to assign ‘selected’ materials to ‘selected’ objects

delete objects
gc()

try (destroydialog X ) catch ()
rollout X ""
(
	MultiListBox obj_list "objects:"
	MultiListBox mtl_list "materials:"
	
	local scene_objects = #()
	local materials     = #()
	
	on x open do
	(
		scene_objects = for i = 1 to 5 collect teapot pos:(random [-300,-300,0] [300,300,0])
		materials     = for i = 1 to 5 collect Standardmaterial diffuse:(random white black) name:("mtl_" + i as string)
		
		obj_list.items = for obj in scene_objects collect obj.Name
		mtl_list.items = for mtl in materials     collect mtl.Name		
	)
	
	on obj_list selectionEnd do 
	(
		select (for i in obj_list.selection where isValidNode scene_objects[i] collect scene_objects[ i ])
	)
	
	on mtl_list selectionEnd do 
	(
		if obj_list.selection.isEmpty or mtl_list.selection.isEmpty do return ok
		
		local objs = for i in obj_list.selection collect scene_objects[ i ]
		local mtls = for i in mtl_list.selection collect materials[ i ]
			
		
		objs.material = mtls[ 1 ] -- but what you're going to do with the rest of selected materials?	

		format "material assignment complete...\n" 
	)
	

)
createDialog X pos:[100,100]

Thank you for your code. It works great on its own. I couldn’t apply it to my code.

I thought I would do the opposite work.

     on rnopti1 pressed do ( if lbx1opti1.selection != 0 then --OK
			
									(	allNodes = for item in lbxSelOBJ1.items collect getNodeByName item --??
										(	if rdo_obj1.state == 2 then --OK
											(if chk_1.checked == 1 then --OK
												( if selection == allNodes do  --??                                                            
													(MyFunctionsStruct.RMa()))))))--random add material

I would like to create the condition “if the object is selected – the name will be in the multilistbox function will be run” so if the object is not in the multilistbox function it will be skipped.

Is it possible to go in this direction?

make a function that takes collection as the argument and do whatever you need with these nodes

fn RandomWirecolor nodes = 
(
    for n in nodes where isValidNode n do n.WireColor = random white black
)
...
...
allNodes = for item in lbxSelOBJ1.items collect getNodeByName item --??
RandomWirecolor allNodes 

I’m broken.

I’ve been trying for weeks to learn how to do it, but I can’t prove it. If you had free time could you write “fn” for me? I managed to make a better multilistbox with callbacks and it works beautifully. I would need to solve two problems so that I can move on.

“fn allNodes nodes arg”

fn chx = chk_1.checked == 1
local scene_objects = #()

fn SelectionChanged = –OK
(
lbxSelOBJ1.selection = for j in selection collect finditem lbxSelOBJ1.items j.name
)
on main open do –OK
(
callbacks.removescripts id:#ID0X7FB0F2910X78FF0B50
callbacks.addscript #selectionSetChanged “main.SelectionChanged()” id:#ID0X7FB0F2910X78FF0B50
)
on lbxSelOBJ1 selected arg do –OK
(
select (for j in lbxSelOBJ1.selection collect getnodebyname lbxSelOBJ1.items[j])
)

fn allNodes nodes arg =
(
for n in nodes where isValidNode collect lbxSelOBJ1.items n.name = object.items n.name
)

     on rnopti1 pressed do ( if lbx1opti1.selection != 0 then --OK
  									(if rdo_obj1.state == 1 then --OK
  										(if chx() then --OK
  											( if allNodes nodes () do                                      
  												(MyFunctionsStruct.RMa())))))--random add material

fn RMa – work good, but
if i have 100 material in listbox and 100object in scene do random a many material for all objects – but i need call random “ONE” material for all selected object – ” i need change defining range?”

fn RMa =
(

            --- defining range
           sc = 0
  		for m in matarrayoptiA do sc = sc + m[2]
  			--- random function in range
            
            --- defining the hit in range
            for o in selection do --= material filename:(lbx1opti1.items [lbx1opti1.selection + (random 0 2 )] )
            (	
                r = random 0.0 sc
                trg = true
                tmpm = undefined
                s = 0
                for m in matarrayoptiA do
                (
                    s = s + m[2] -- greater limit
                    if r <= s then 
                    (	
                        if trg then 
                        (	
                            --print m[1].name
                            tmpm = m[1]
                        )
                        trg = false
                    )
                ) -- end for matarray
                try
                (
                    o.material = tmpm
                    o.material.showInViewport = true
                )
                catch()
            ) -- end for selection

I’m losing strength, thank you

I changed the whole functionality because it was not very logical. I’m working with an ID now. This is my new structure.

new schema.jpg930×596 89.8 KB

Sel OBJ Group – working good.
fn = select obj – assign constant value ID (add in modifier material with ID value and collaps – all face change id)

fn Randomize Materials = assign material from multilistbox on selected obj in scene.

I would need to specify the ID in the material randomize.
If sett value ID 1 assign material for only OBJ with ID 1
but, I will have a selection of many objects with different IDs

Is it realistic to do this?

Sorry,

For example: I have two objects “box1 – has ID 1” and “box2 – has ID2” / ID is meant as $ .EditablePoly.setMaterialIndex 1 – element /, I need to solve this problem: If I select “box1” and “box2 “together, material will only be added to” box1 “.

I don’t know how to proceed. Do I have to use a g-buffer object ID? Or is it possible to set my material list as Multi-Sub material? How would the easiest way to solve this problem?

Why it should work like that?
