Note: You can install RMX for Glyphs 2 and RMX for Glyphs 3 side-by-side, as each version of Glyphs has its own Plugins folder. Copying the file manually into the folder will not work as macOS will not trust the plug-in. Just drag the RMX.glyphsFilter file onto the icon in the dock, and make sure you install the right RMX version that matches the Glyphs version. Finally, don’t forget to re-start Glyphs!
Other than working smoothly in Glyphs 3, the latest version of RMX has a bunch of other improvements:
Better support for files with a great number of masters.
Support for multi-dimensional brace layers.
Improved accuracy when changing the width of italics.
Fixed handling of nested components.
Non-master layers are no longer removed from scaled glyphs.
The RMX Harmonizer is now even more stable with complex Bézier curve structures.
The RMX Scaler now always scales the sidebearings, the gear menu option has gone.
The updates in the preference overlapped too much with the plugin-manager. And the plugins that are not in it, had different requirements. So would prefer if you could add that check yourself. I can help with that.
Did you drag-and-drop the right RMX version onto the Glyphs 3 icon on the dock? Did you re-start Glyphs? If you press Cmd+Shift+Y, and look inside the Plugins folder, do you see the file RMX.glyphsFilter? If you select it and press Cmd+I, which version does it say?
@danielquisek That bug should be fixed now. Thanks again for reporting it. @George_Thomas Hopefully your crashes are also fixed now. If you experience any further crashes please let me know.
Also, this version of RMX checks for available future updates. Glyphs 3 does not check automatically for plugin updates (for independently installed plugins) any more so you will not be notified of today’s update in Glyphs 3 (only in Glyphs 2) but in future RMX will check and tell you directly (in Glyphs 3, that is). Phew.
RMX Tuner and RMX Harmonizer should be working flawlessly with any number of masters now. And I am working on a new layer-based palette tool that will probably replace RMX Scaler and RMX Monospacer at some point. Hope that helps for now!
