I created a mask. When I apply it to albedo or AO it loads properly and cover what's intended to be. But when I apply it to roughness it becomes weird. All maps are the same dimensions.
That is strange, I'll investigate and get back with you.
I've been able to replicate the bug. It looks like the problem also exists on the metalness map. I'll update the plugins and issue a patch release in the next couple of days.
Thanks for bringing this to my attention.
Just an update. It looks like the next release (with the bug fix) will be available on or before Monday, September 9th Tuesday - September 10th 2019. Thanks for your patience.
