[Closed] Reading the object(s) from material browser?

Also im trying to delete a material slot from a multisub object thats unused, (i guess if i cannot get it working ill set it as standard)

Ok when i do the following

deleteitem scenematerials[1].materialList 1

It deletes the last material, not material number 1. Why is this? How do i delete material 1 and leave the rest?

Cheers

oh, one other thing…

when i use the following bellow, how can i convert it to an array of values, thats not “linked” to the materialIDList?

tmp = copy scenematerials[1].materialIDList
#(2, 4, 6)
tmp as bitarray
-- Unable to convert: #(2, 4, 6) to type: BitArray

Is there a way to read the objects list for each material from the “material/map browser”?

Or do i need to sort through all object in the scene and build my own array of objects?

you could try something like this:

themat = meditmaterials[1]
nodes = for i in refs.dependents themat where isvalidnode i collect i

this will get the objects that the material depends on in the scene… although im not sure if this method would apply seamlessly on every scene…

maybe you could try collecting the materials that you need on a temp array, build a new multimaterial out of those array, and replace the current one…

when i use the following bellow, how can i convert it to an array of values, thats not “linked” to the materialIDList?

tmp_arr = scenematerials[7].materialIDList as array
tmp_bit = tmp_arr as bitarray
tmp = copy tmp_bit

although i can’t guarantee that the above is your best solution for this one.

ok cool, thanks.

So with makign my own multimaterial array, will i only need to store the name of the material, and the ID(materialList and materialIDList) ?

Here’s an example function that will remove a given material (by index or by ID) from a multimaterial. The only problem with this is that max screws up the material if you perform an Undo afterwards…
