The More Quality Scaling mod adds quality effects by making quality-specific copies of entities and substituting them at runtime (for pipes, this includes length scaling and/or quality-specific connection categories for "weaving"). For compatibility, I would need to inform your mod of those copies - you could just read out prototypes.mod_data["entity-clones"].data[original_name] for an array of related copies and adapt the rotation code from that, but if you added an interface allowing access to the rotation table etc., I could manually add rotation entries for the quality variants on my side.

The easiest implementation on your side would be changing the interface to the following in your script/rotate-and-toggle.lua:

remote.add_interface(script.mod_name, {get_pipe_table = get_pipe_table, get_ignored_pipes = get_ignored_pipes,get_master_table=function() return advancedPiping end})

This should let me add all the quality-specific entries to the table from my side.

There's an interface in there now. Does it require the additional parts you added after it?

Yes, the rotation tables are currently not exposed, and I need to add entries for the quality variants to those so higher quality AFH pipes can still be rotated.

I've had a request to support AFH pipe rotation in 2.0 as well, so ideally the interface would be available in that Factorio too branch as well, so those user(s) don't need to manually modify local mod files.
