How do I do an opacity map when I use Udim method?

V-Ray V-Ray for Maya General

I worked on the texture in the udim method

I worked on 1001 to 1005.

What should I do when the opacity map is included in the 1005 tiles only?

I pulled the file in Png format.

What should I do?​

You need to use the wildcard <UDIM>. Check docs.
