Modifier property checking if exist or not

Description

Hello everybody,

I’m a beginner considering Maxscript (and also new on this forum),
I'm trying to create a script that select objects by a material modifier.materiaID property
I found a few lines from a certain @Swordslayer (great thanks to him \m/ by the way) it works perfectly but to finalise it, I would add an option like
if the value set by user doesn't exist in all materialmodifier in the scene, script will show up a message box like "nothing match" or something :D

This is what I got now
Someone can help me please :)

rollout MtlID "MtlIDtools" width:281 height:158
(
spinner 'spn2' "" pos:[197,126] width:56 height:16 align:#left type:#integer range:[0,100,0]
on spn2 changed val do

(
local objs = #()
local mods = getClassInstances MaterialModifier
for m in mods where m.materialID == a do
(
if (a==val) then
(
join objs (refs.dependentNodes m)
select objs
)
else
(
messagebox "Nothing Match!"
)
)
)
)
createDialog MtlID

or juste a few which check if the materialID is used or not in the scene would be so cool
Thank you all

I don't have a proper scene to test so try this:


rollout MtlID "MtlIDtools" width:281 height:158
(
	spinner 'spn2' "" pos:[197,126] width:56 height:16 align:#left type:#integer range:[0,100,0]
	on spn2 changed val do

	
	local objs = #()
	local mods = getClassInstances MaterialModifier
	for m in mods where m.materialID == a do
	(
		if (a==val) then
		(
			join objs (refs.dependentNodes m)
-- 			select objs
		)
	)
	if objs.count == 0 do
	(
		messagebox "Nothing Match!"
	)
)
createDialog MtlID

oh yeaah thank you ;)
I tried this and seems works fine but not sure if it is the best way :D

rollout MtlID "MtlIDtools" width:281 height:158
(
spinner 'spn1' "" pos:[197,126] width:56 height:16 align:#left type:#integer range:[0,100,0]
on spn1 changed val do
(
local objs = #()
local mods = getClassInstances MaterialModifier
for m in mods do
(
if (m.materialID == val ) then
(
join objs (refs.dependentNodes m)
select objs
)
)
--if not then deselect all and show up message
if (objs.count < 1) then
(
messagebox "Nothing Match!"
deselect $*
)

Why do you need to select the objs?


rollout MtlID "MtlIDtools" width:281 height:158
(
	spinner spn1 "" pos:[197,126] width:56 height:16 align:#left type:#integer range:[0,100,0]
	
	on spn1 changed val do
	(
		local objs = #()
		local mods = getClassInstances MaterialModifier
		for m in mods do
		(
			if (m.materialID == val ) then
			(
				join objs (refs.dependentNodes m)
				--	"why you need the next line?"
-- 				select objs
			)
		)
		--if not then deselect all and show up message
		if (objs.count < 1) then
		(
			messagebox "Nothing Match!"
			max select none
		)
	)
)
createDialog MtlID

Since I can't select object by material ID on a Multi-sub material, I thought of this script,
It scan and select all the object with a specific materialID assigned on it
I usually works with poly select + material modifier instead of collapsing all to an editable poly or mesh to keep my mod dynamic (line+shell...) and lightweight max file
I don't know if it is the best way to work but that is how I did till now
Let me know if you have a suggest ;)
Cheers and mega thanks to you @miauu
