Только что для этого написал еще один скрипт на Python для Cinema4D.
Подробную информацию можно найти в блоге тревожных СМИ и вики .
Для справки, я также перечисляю источник здесь:

Export meshes the three.js 3D Engine by mr.doob's et al.
More details on the engine here:
https://github.com/mrdoob/three.js
Currently supports UVs. If the model doesn't display correctly
you might need to reverse some normals/do some cleanup.
Also, if you use Selection Tags and basic ColorMaterials,
the colours will be picked up as face colors. Call autoColor() on the
model you use for this.
The mesh transformations(position, rotation, scale) are saved
and you can get them using: getPosition(), getRotation() and getScale()
each returning a THREE.Vector3
In short
var myGeom = new myC4DGeom();
var myModel = new THREE.Mesh( myGeom, new THREE.MeshFaceMaterial());
//set transforms
model.position = myGeom.getPosition()
model.rotation = myGeom.getRotation()
model.scale = myGeom.getScale()
//set selection tags colours
myGeom.autoColor()
More details on this exporter and more js examples here:

Have fun!
This script requires Cinema 4D R11.5 minimum and the Py4D Plugin:

Кроме того, добавлены «тонкие» экспортеры в репозиторий , который должен создавать файлы меньшего размера .js.
