Hello, I have been looking into simplying the build process for Cura. At present, it is quite difficult to build Cura from scratch. One large part of this is the...

MeshBuilder.addIndices vs MeshBuilder.setIndices both set the self._indices to the input indices argument (so I am guessing they expect the same input), but they calculate the new self._face_count differently: https://github.com/Ultimaker/Uranium/blob/master/UM/Mesh/MeshBuilder.py#L124 https://github.com/Ultimaker/Uranium/blob/master/UM/Mesh/MeshBuilder.py#L352...
