KM-3D released Smooth Boolean 2, a new version of a commercial plugin for 3ds Max that lets artists create smooth transitions between ProBoolean meshes. The update adds the ability to handle low-poly meshes, brings improved handling when mixing meshes of different resolutions, and more. There's also improved strips selection, easier debugging, plus a cleaner output mesh.
What is more, the latest version adds two useful new modifiers: the Smooth Bridge modifier to seamlessly bridge two open edgeloops even with an uneven edge count, plus the sbNormalMap modifier to restore smooth explicit normals on edited SmoothBoolean object.
