Ashley - I might have a few ideas for the future of C3 if it is implementable.
My Suggestions for C3:
+3D and 2D separate interface - A 2D or 3D option in the "project properties bar" or in the "new dialog" or in the "view menu". Whichever is efficient.
+C3 image editor that can make transparent images, aspect ratio resize or scale, gradient and shapes and also multiple images can be placed inside the image editor to be edited, crop and other useful features of an image editor.
+Behaviors can be made using the event sheet but still save the option to make a behavior using javascript.
+More coloring and lighting features. ( I don't know much about this , I hope you get the idea.)
+!!!Most Importantly!!!(Exclamation point for emphasis) C3's own native export option to make life easier.
That's it for now. The most important is the native export out of all.
There won't be native export nor 3D. Ashley said obvious reasons for this. If you're interested, search the forum.
