I have successfully got a plugin built and running on the Mod.
Now I’m looking at getting the gui done.
Naively I though that Mod Sdk would do that for me after running the wizard but that doesn’t seem to be the case (although it does seem to work with the x64 version running in mod app!)
the sdk creates a new folder with just the new modgui in your lv2 directory (or at least tries to) you can then copy the data out of this into your plugin source or bundle modifying ttl as necessary (you will need to integrate the 2 manifest.ttl).
