New release of 3D Object with major changes. It now supports GLTF models with animation thanks to R0J0hound's code that parses gltf and does animation.
I added some animation ACEs and ZElevation ACEs, expressions and control for ZScale ACEs.
It does not yet render in Editor (as I did for obj files) but I will be working on that. It now renders in editor.
You can try it here, it is still under development:
kindeyegames.itch.io/c3-3dobject-alpha
Also if Scirra is interested in integrating this into C3 directly, please feel free to contact me, I would be happy to share it (I know they may not because dealing with 3D models, formats, performance, etc. is a bit complicated in terms of user expectations for simple integration in C3 or they may be planning something else already.)
Example with 3D object, 3D shape, 3D camera.
