Help with newest interface. I am lost.

[ClaraSanders]

I've been using Super Merger in Automatic1111 for months, a relatively old version. Last month it stopped working and I was forced to use the latest version...and well, I don't know how it works anymore, I am clueless. All I want is what I used to do before, take an overtrained model with a style and transfer the difference to Dreamshaper by subtracting SD 1.5 using block by block merge. Where do you define how much data want to merge on the new interface? I want to transfer all, wich means "1" but where do you define this parameter? If I select MBW the alpha parameter disappears. Sorry if this is a stupid question, but I am not AI-savvy.
