<Unwrap_UVW>.setSelectMatID not updating

[Anonymous]

Hello,

 I am using the maxscript method <Unwrap_UVW>.selectByMatID and <Unwrap_UVW>.setSelectMatID. However it seems to only update the UI spinner value and not execute it.

Does anyone know how to “Enter” this value or what Im doing wrong?

Here is example on how Im using it.

(
	for i=1 to listA.count do
	(
		$.modifiers[#unwrap_uvw].selectByMatID listA[i]
		$.modifiers[#unwrap_uvw].setSelectMatID listB[i]
	)
)

If you have a box selected with a Unwrap UVW modifier applied and run the following in the listener window.

$.modifiers[#unwrap_uvw].selectByMatID 2

$.modifiers[#unwrap_uvw].setSelectMatID 1

You’ll see in the Material IDs rollup window SetID: 1 and SelectID: 2 instead of SetID: 1 and SelectID: 1 (what happens when you manual use the spinner or press Enter)

Im working in 2017, but tested this in 2016 and 2018 as well with the same result.

Any help would be great!

use setSelectionMatID if you want to update SetID as well
