Not for now. Our vision is to create a new minimalist and digital art style, which we call "Capsule Design", and which is more like pixel/voxel art or low poly design. The rule is to use only capsules and shapes extended from capsules.
That being said, some contributors, including Capsule's founder Maxime, have already developped advanced tools for implicit modeling, which allows for smoothing and polygonizing capsules. We are considering the possibility to setup a dedicated modeler for that, let us know if you are interested.
