Davio made me do ^^^that lmao.
Yea, if your willing to make a 3D game without 3D objects or any modeling tools, it's certainly possible to have animations and cameras and an in-game model editor with texture loading... but that's building the whole engine up from the ground yourself. It took a LONG time to make things look right, the thumbs are spawned using expressions nested in expressions using multiple variables to create a point cloud that deforms properly, and then ontop of that you need to map square meshes onto that point cloud, handle all the rotations math and so forth, its really, really, really, slow and complicated.
basically thumbs was created to prove that construct's event system and basic sprite object are able to do pretty much ANYTHING , but that doesn't mean it's easy. Of course for simpler 3D games you could make like starfox or something without TOO much work, well if you were good enough with constuct at least.
in short answer, traditional style 3d animation is impossible right now in construct, you need to build your own system to do it, and thats certainly not EASY, especially if you've never did any 3d programming/math before.
