MMU2 with soluble support material not generating bridges
I've got a large model that for prototyping has been modified specifically for 3d printing so that only the bottom 3mm needs supports (disregard the unsupported circular openings though - I haven't fixed those yet.) The rest (higher) portions of the model make extensive use of bridging, which drops my print times from 3-4d to 1d. However when I switch from a single material (support only for enforcers) to multi-material (support only for enforcers) the bridging disappears (pics below). That happens both with soluble-full and soluble-interface only settings. Toggling Print Settings - Support Material - Don't support bridges doesn't have an impact. Does anyone know of the setting that controls the use of bridging when using the MMU2 with soluble support material?
Sliced in single-material mode with support enforcers (bridging generated correctly):
