I'm still learning to use blender, I tried your plugin for 3d animation and it worked, but when trying to create a box without animation the image size is different. Should 3d objects use animation or not?
Can you send your project? You can also take a look at setting zScale for the box (to 3DCamera.zScale on load.) Hard to tell what you expect here without seeing blender model and then C3 preview.
