Hi,
Is there a sure-fire way to retreive all of the used MaterialID (effects channels) in use in a scene?
Think about it, it is a little tricker than it first seems. Ideally I would like something that retreives all max classes that have this property, and then search through those to get their values. If I search through scenematerials and filter out materials then it will not get any sub-materials that have an effects channel.
OK, thanks in advance.

using what JHN posted in the other thread…
for mat in material.classes where (local mats = getClassInstances mat).count > 0 do
(
)
Thanks,
I was looking at Johans code for the answer but it was not immediately obvious to me
matIDs=#{}
for mat in material.classes where (local mats = getClassInstances mat).count > 0 do for m in mats where m.effectschannel!=0 do matIDs[m.effectschannel]=true
matIDs
J.
or minimal version
ids = #{}
for mat in material.classes do for m in (getclassinstances mat) do append ids m.effectschannel
ids
Hi Denis,
Yep, that will do it, thanks.
J.
Great and thank you! I’m looking for this a while.
I just have one question. I’d like to make a button and see #s in a message box not listener. I try to create it but not works… I’m learning script but still don’t know deep.
Please give me some advice!
rollout UsedID “Used Material ID”
(
button showID “numbers”
fn getIDs =
(
ids = #{}
for mat in material.classes do for m in (getclassinstances mat) do
append ids m.effectschannel
ids
)
on showID pressed do
(
index = getIDs()
messageBox (index as string)
)
)
createdialog UsedID
It shows #s but not clear… how to copy listener info (#s) to message box?
Please and thank you.
