Title: CoronaSelect - Maxscript
Post by: Alex Abarca on 2024-08-21, 23:11:48

Hi All,

Does anyone have a script that looks in the scene's material for CoronaSelect nodes and the toggles the CoronaSelect from 0 to 1?

I have decals that needs to switch from ON and OFF in the scene.

Thank you!

You could do something like this:

Code: [Select]

(
    -- Collect Corona Materials from Slate Material Editor selection
    local selected_materials = #() 
    if (sme.getview sme.activeView) != undefined then 
    ( 
        selected_nodes = (sme.getview sme.activeView).GetSelectedNodes()   
        if selected_nodes.count != 0 then 
        ( 
            for node in selected_nodes do 
            ( 
                if (superclassof node.reference == material) then 
                ( 
                    if classof node.reference == CoronaPhysicalMtl or
                       classof node.reference == CoronaLegacyMtl then
                    (
                        append selected_materials node.reference 
                    )
                ) 
            ) 
        )
    )

    -- Toggle Corona Select 0 or 1 (does not support more than 0 or 1)
    for i in selected_materials do
    (
        for cSelect in (getClassInstances CoronaSelect target:i) do 
        ( 
           if cSelect.selected == 0 then
           (
                cSelect.selected = 1
           )
           else
           (
                cSelect.selected = 0
           )
        )
    )
)

Notes:
- Supports 0 or 1, if you need additional "map count" then you would have to change the script.
- Works on selected material in Slate Editor (not selected objects or child nodes in the Slate Editor).
- If you have 2 materials sharing the one Corona Select node only pick one of the materials (in your screenshot for example).

Also if you just want to do it scene wide without having to select materials you could use this instead:

Code: [Select]

for cSelect in getClassInstances CoronaSelect do
(
    if cSelect.selected == 0 then
    (
        cSelect.selected = 1
    )
    else
    (
        cSelect.selected = 0
    )
)

Thanks, James! I have to say, both scripts are pretty nifty, and I can see the use cases for each. However, in my case, I need to remove logos from library objects that are scattered across the scene, and this is something I have to deal with regularly. Given my situation, I prefer the second script. Appreciate the help!

You're welcome! Yes feel free to use which is best for your situation. I figured someone might also want the first script so I kept both here in case.

It wouldn't be hard to a toggle for one with 100+ "map count"(s) either but I only spent 30 seconds on each so that will do for now lol.

Also just be aware its just a toggle, so this is assuming you keep your workflow consistent, if you somewhere along the line decide to flip 0 with 1 in your CoronaSelect then you will encounter unexpected results.
