Bake mech with multiple material sets via python

Hi guys,

I'm baking a lot of stuff in marmoset using python api, however today I've found that when I set baker.multipleTextureSets = True Marmoset found 0 texture sets in my model: baker.getTextureSetCount() retrns 0. Model is ok and have materials properly set: if I select baker in scene tree view by hand it refreshes its data and now it is ready to bake.
That's pretty annoying because I bake tens of similar objects in a batch, so I don't want to do it by hand each time.
How can I make marmoset to select my baker in list? I can't access its GUI, only to created by script.
Or maybe there is a way to make my baker update texture set list in python?
Thanks!

Just in case here's my code. Of course forum will kill all the identation but you'll got the idea. I set environment vars before launch it.

mset.loadScene(template_scene)
