I would also like to inform that the C3 SDK has some interesting features that you might like to use. Those include,
Editor :: Preview. Draw and Preview plugins on the editor. Potentially can be useful for showing and previewing the initial animation/frame of the Spriter Plugin even while on the editor.
Custom Importer :: Drag files to import into Construct 3 and make events, objects, instances, container and families automatically like on Construct 2.
Drawing :: The C3 SDK already had drawing features available on the initial release. So, by now, it is stable enough to be supported. And a few already made use of it.
There are probably a lot more. But I recommend you guys checking it out yourselves.
Thank you in advance.
